If cancer is diagnosed at the second stage, then from 70 to 80% of patients recover, at the third stage the chance is significantly reduced to 30-35%. However, it can be very difficult to detect cancer in the early stages, since it has practically no signs. However, if you listen to your own body, the tumor can be detected.

The difficulty in treatment lies also in the fact that the detected disease in the early stages does not require large material costs. Whereas in the future, only big money for the latest drugs and numerous treatment procedures will help cure cancer.

From the very beginning of its formation to the final result, cancer lives in the body for about 10 years. To date, there are about 200 varieties of malignant tumors. And each of them can be cured if you consult a doctor in time. 80% of cancers are considered self-created. It is difficult to get close to the owners of strong immunity, a healthy lifestyle and an optimistic mood of this disease.

Cancer can also provoke environmental pollution, unclean water, polluted air and a sedentary lifestyle. Improper nutrition also gives impetus to the formation of a malignant tumor. Therefore, in 75% of the food should be predominantly of plant origin and only 25% of the animal. People who regularly eat excessively "effective" diets also contribute to tumor formation. Relatives of cancer patients are also at risk.

Symptoms suggestive of cancer

Despite all these statistics, you could already significantly spoil your health. Moreover, environmental pollution or a harmful lifestyle does not determine 100% of the formation of cancer. A malignant tumor affects everyone without exception, regardless of status, place of residence and age. And you should be wary if you regularly notice some signs of this disease:

If you have ulcerative wounds that do not heal for a long time;

If causeless bleeding and spotting appear;

If seals are palpable, foreign formations on the body;

If digestion or swallowing reflex is disturbed;

If you have one large or several new moles that have an unusual color, shape or size. Cancer can manifest itself in an existing mole, which in turn will also change color, shape or size;

If you have been suffering from cough, shortness of breath and hoarseness for a long time;

If you regularly suffer from headaches;

If you have noticeably lost weight in a few months and have no appetite at all;

If you feel pain in the bones;

If you get tired very quickly, you feel weakness in the whole body;

If for no apparent reason you have a fever;

If you often get sick;

If sweating and dizziness appear;

If swelling is felt in the area of ​​the lymph nodes. In the area of ​​​​the neck, armpits, inguinal areas;

If cracks and ulcers form on the skin, tongue, gums, palate, and so on;

If you are unable to swallow food normally;

If you feel a regular feeling of heaviness in the stomach, abdomen;

If painful sensations appear in the chest, the cough is characterized by the presence of bloody discharge;

If you notice a sharp decline in vision.

Each of these signs should be the reason for going to the hospital. And this does not mean that you will be given a terrible diagnosis. These signs can also appear in other diseases, which should also be treated. Since chronic diseases also provoke cancer.

According to medical professionals, tomography of the whole body should be performed at least once every two years. So you can prevent the occurrence of serious diseases. And not just malignant tumors.

In some cases, it is enough to undergo an ultrasound or fluorography, as well as an x-ray and microscopic examination of sputum.

You should also know how many stages of cancer development there are:

1. The first stage is characterized by DNA damage, which is treated with ultraviolet radiation, radioactive and chemical substances. The initial stage is characterized by uncontrolled cell division, but almost 100% of the fact that this can be cured immediately.

2. At the second stage, these very "fertile" cells begin to form a tumor, grow. Nevertheless, the tumor in 70-80% can be cured.

3. At the third stage, cancer cells are able to form metastases, which can spread throughout the body through the lymph and blood. However, the tumor can still be cured in 30-35% of cases.

4. But at the fourth stage, there is practically no chance to be cured. In this case, cancer spreads everywhere - to nearby and other organs, cancer affects the entire body, tumors appear in different parts of the body.

Therefore, to identify cancer in the early stages of development should be the task of everyone!

Malignant tumors: signs, causes and methods of treatment

A terrible diagnosis like cancer, everyone is afraid to hear. And if earlier such malignant processes were found only in the elderly, today such a pathology often affects young people up to 30 years of age.

Is a malignant tumor cancer or not?

The formation of malignant origin is the uncontrolled reproduction and growth of abnormal cells that contribute to the destruction of healthy tissues. Malignant tumors are dangerous for general health, and in some cases are a threat to life, because they metastasize to distant organs and are capable of invasion into nearby tissues.

How is it different from a benign tumor?

Distinctive features of oncology of a benign nature is the fact that such a tumor is located in a kind of capsule that separates and protects the surrounding tissues from the tumor.

The malignant nature of the tumor gives it the ability to grow into neighboring tissues, bringing severe pain and destruction, metastasizing throughout the body.

Abnormal cells divide easily and spread through the body through the bloodstream, stopping in different organs and forming a new tumor there, identical to the first one. Such neoplasms are called metastases.

Poor-quality formations are divided into several varieties:

• carcinoma or cancer. It is diagnosed in more than 80% of cases of such oncology. Education is formed more often in the intestine, lungs, mammary or prostate gland, esophagus. A similar tumor is formed from epithelial cells. Appearance varies according to location. In general, they are a node with a bumpy or smooth surface, hard or soft structure;
• Sarcoma. It grows from the cells of muscle and bone connective tissue. It is quite rare (1% of all malignant oncologies) and can be located on the skin, in the uterus, bones, joints, in the lungs or soft tissues of the thigh, etc. Such a tumor is characterized by transient growth and metastasis. Often, even with early diagnosis and removal, it recurs again;
• Lymphoma. Formed from lymphatic tissues. Such neoplasms lead to violations of organic functions, since the lymphatic system, designed to protect the body from infectious lesions, in the presence of a tumor cannot perform its main tasks;
• Glioma. It is formed in the brain, growing from glial nervous system cells. Usually accompanied by severe headache and dizziness. In general, the manifestations of such a tumor depend on its localization in the brain;
• Melanoma. It grows from melanocytes and is localized mainly on the skin of the face and neck, extremities. It is rare (about 1% of all malignant tumors), characterized by a tendency to early metastasis;
• Leukemia. It grows from stem cells in the bone marrow. Basically, leukemia is a cancer of the blood-forming cells;
• Teratoma. Consists of embryonic cells, formed even in the prenatal period under the influence of pathogenic factors. Most often localized in the testicles, ovaries, brain and sacrum;
• Choriocarcinoma. It develops from placental tissues. It is found only in women, mainly in the uterus, tubes, ovaries, etc.;
• Malignant tumors that form in children under 5 years of age. These include various tumors such as osteosarcoma, retinoblastoma, lymphoma, nephroblastoma or neuroblastoma, neurological tumors or leukemia.

Causes

The main predisposing factor to the formation of tumors of a malignant nature is heredity. If several cancer patients are found in the family, then all household members can be registered.

Equally important is the presence of nicotine addiction. Unfortunately, even a photo of cancerous lungs posted on a pack of cigarettes does not repel smokers from this addiction. Tobacco smoking most often leads to the development of lung or stomach cancer.

In general, experts distinguish only three groups of factors predisposing to the development of cancer:

1. Biological - this group includes various viruses;
2. Chemical - this includes carcinogens and toxic substances;
3. Physical - represent a group of factors, including UV radiation, radiation exposure, etc.

All of the above factors are external. Experts refer to genetic predisposition as internal factors.

In general, the mechanism of cancer development is quite simple. Our cells live for a certain time, after which they are programmed to die, and they are replaced by new ones. So the body is constantly updated. For example, red cells in the blood (or erythrocytes) live for about 125 days, and platelets - only 4 days. This is a physiological norm.

But in the presence of pathogenetic factors, various failures occur and obsolete cells, instead of death, begin to multiply on their own, producing abnormal offspring, from which tumor formations are formed.

How to determine a malignant neoplasm?

To determine the malignant tumor process, it is necessary to have an idea about its symptoms. So, malignant oncology is characterized by the following main features:

• Pain. It can appear at the beginning of the tumor process or occurs with its further development. Often disturbed by pain in the bone tissue, and there is a tendency to fracture;
• Signs of weakness and chronic fatigue. Such symptoms occur gradually and are accompanied by a lack of appetite, hyper sweating, sudden weight loss, anemia;
• Fever state. A similar symptom often indicates a systemic spread of the cancer process. Malignant oncology affects the immune system, which begins to fight hostile cells, which is why the state of fever appears;
• If the tumor does not develop inside the body, but close to the surface, then a palpable swelling or induration can be detected;

In the photo you can see a seal on the skin, this is what a malignant tumor looks like - basalioma

• Against the background of a malignant tumor, a tendency to bleeding may develop. With stomach cancer - this is bloody vomiting, with colon cancer - feces with blood, with uterine cancer - bloody vaginal discharge, with prostate cancer - semen with blood, with bladder cancer - bloody urine, etc.;
• Against the background of a malignant tumor process, an increase in lymph nodes occurs, neurological symptoms appear, the patient often undergoes various inflammations, any rashes on the skin or yellowness, sores, etc.

The general symptomatology increases gradually, supplemented by new signs, the condition gradually worsens, which is associated with toxic damage to the body by the products of tumor vital activity.

Ways of metastasis

Malignant tumors tend to spread to other organs, i.e. to metastasize. Usually the stage of metastasis occurs already in the later stages of the tumor process. In general, metastasis occurs in 3 ways: hematogenous, lymphogenous or mixed.

• Hematogenous way - the spread of the cancer process through the bloodstream, when tumor cells enter the vascular system and are transferred to other organs. Such metastasis is typical for sarcomas, chorionepitheliomas, hypernephromas, lymphomas and tumors of the hematopoietic tissue;
• The lymphogenous pathway involves metastasis of tumor cells through the lymph flow through the lymph nodes and further into nearby tissues. This path of spread of metastases is typical for internal tumors such as cancer of the uterus, intestines, stomach, esophagus, etc.
• The mixed path involves lymphogenous-hematogenous metastasis. Such a spread of the tumor process is characteristic of most malignant oncologies (cancer of the breast, lung, thyroid gland, ovaries or bronchi).

Stages of development

When diagnosing, not only the type of malignant formation is determined, but also the stage of its development. There are 4 stages in total:

• Stage I is characterized by a small size of the tumor, the absence of germination of the tumor in neighboring tissues. The tumor process does not capture the lymph nodes;
• Stage II of a malignant tumor process is characterized by a clear definition of the tumor within its initial localization, although there may be single metastases in the lymph nodes of regional significance;
• Stage III is characterized by the germination of the tumor in the tissues lying around it. Metastasis in regional lymph nodes becomes multiple;
• At stage IV, metastasis spreads not only to the lymph nodes, but also to distant organs.

Diagnostic methods

Diagnosis of oncology of a malignant nature consists in the following procedures:

• X-ray examination, which includes:

1. X-ray computed tomography;
2. Endoscopic examination;
3. Ultrasound diagnostics;
4. Nuclear magnetic resonance;

• Radioisotope diagnostics of tumors of malignant origin, which includes:

1. thermography;
2. radioimmunoscintigraphy;
3. Detection of tumor markers;
4. Study of the level of chorionic gonadotropin;
5. The level of cancer-embryonic antigen, etc.

Treatment

Malignant formations are treated by three methods: medicinal, radiation and surgical.

Drug therapy consists in the use of specialized drugs for chemotherapy:

• Antimetabolites like Methotrexate, Ftorafura, etc.;
• Alkylating agents - Benzotef, Cyclophosphamide, etc.;
• Herbal medicines like Kolhamin, etc.;
• Antitumor antibiotic drugs - Chrysomaline, Bruneomycin, etc.

2 Comments

It must be said in addition that the final diagnosis of "cancer" can only be made on the basis of the results of morphological studies - histology and immunohistochemistry. Any X-ray diagnostics only helps to make a diagnosis and determine the parameters of the neoplasm. Although, in the ideal case, radiation diagnosticians and pathologists work together (this option is now implemented in a private direction, at UNIM). And then, based on the results of morphology, a decision is made.

Yes, until an accurate diagnosis of cancer is made, it will take at least 15 days until the treatment is started for another 15 days, so we lose precious time.

How to identify a benign or malignant brain tumor

How to identify a malignant tumor

A malignant tumor is a neoplasm whose cells divide uncontrollably and are prone to metastasis. In the initial stages, it is almost impossible to detect it by external signs. In order to identify the disease in the early stages, when it is most easily treatable, it is necessary to conduct a medical examination for prevention.

How to identify a malignant tumor?

Diagnosis of a malignant tumor

First of all, take a blood test for tumor markers. This type of diagnosis helps to determine the presence of malignant cells in the body. In the event that the analysis confirmed the presence of oncomarkers in the blood, then an additional series of studies is assigned.

Get diagnosed with a malignant tumor using ultrasound, computed tomography and magnetic resonance imaging, x-rays and mammography. The examination method directly depends on the organ that needs to be checked. For example, a malignant tumor of the breast can be detected using mammography, and malignant neoplasms of the larynx are detected using microlaryngoscopy or fibrolaryngoscopy. In the first example, the organ is examined with an endoscope, in the second case - with a microscope. Malignant tumors of the fundus, body of the uterus and its cervix are diagnosed using an endoscope. A similar method is used to check the colon for malignant growths. When using all of these methods, a tissue sample is used to detect the tumor, which is sent for a biopsy. This procedure is final, it allows you to make a final diagnosis.

Determine the presence of malignant tumors using immunomagnetic enrichment technology. At present, this is the most modern method for diagnosing this type of disease. To do this, you need to take a blood test, in which, during the laboratory examination, the amount of Veridex CellSearch is determined. A large number of cells of this type indicates a 100% probability of a malignant tumor in the body.

Later, advanced stages of the disease are determined by palpation during self-examination or during a medical examination.

I would like to note that in the first place, everyone should not be concerned about the question: How to determine a malignant tumor? but how to prevent its occurrence. To do this, you need to maintain a normal state of the immune system. It is she who recognizes and immediately destroys all unnecessary and alien cells.

How to identify a brain tumor?

One of the most serious diseases today is a brain tumor. The outcome of the disease directly depends on the structure, type, location and size of the neoplasm. Only modern diagnostics can save a person's life.

Diagnosis of a brain tumor

Any tumor can be either benign or malignant. However, the absence of cancer cells does not always mean that nothing threatens a person's life. Benign neoplasms are no less dangerous than malignant ones, as they can cause disturbances in the vital functions of the brain and compress tissues and blood vessels.

Headache is the main symptom of a brain tumor. If it intensifies in the morning and is accompanied by nausea or vomiting, you should be wary. These symptoms are present in the majority of patients with a confirmed diagnosis, although they do not always indicate the presence of a neoplasm. In order to exclude a brain tumor, it is necessary to undergo an examination.

Sooner or later, a brain tumor begins to cause a violation of vital functions. And only the location of the tumor depends on what symptoms it manifests itself. Tumors of the frontal lobe lead to memory impairment, with a tumor in the temporal lobe, hallucinations may appear, in the parietal lobe - convulsions, and if the occipital lobe is affected, coordination of movements is disturbed.

In addition, the character may deteriorate, numbness occurs in the limbs, speech, vision and hearing are disturbed, and the ability to concentrate is reduced. If you or someone close to you has these symptoms, you should immediately consult a doctor.

But do not forget that identifying symptoms is only the first stage of diagnosis. Further, under the supervision of a doctor, a complete examination will be carried out. First of all, consult a neurologist who will give an objective assessment of your condition and give further recommendations.

Also make an appointment with an optometrist. When examining the fundus, it is often possible to identify abnormalities that indicate a neoplasm.

Another reliable way to determine a brain tumor is magnetic resonance or computer diagnostics. They allow you to make a final diagnosis and tell if there is a neoplasm. In order to obtain the most reliable result, it may be necessary to introduce a contrast agent into the body. The diagnosis can be found out after half an hour of examination.

Prognosis for the life of patients with benign and malignant brain tumors

Brain tumors are a group of diseases that occur in 20 people out of the population. All tumors of the central nervous system are divided into benign brain tumors and malignant. However, the course of the process, caused by both benign and malignant neoplasms, is severe.

The etiology of any tumors is unknown. There are only various assumptions why this disease can develop. In most cases, neoplasms occur spontaneously, without any connection with environmental factors or the state of the body. In some cases, a hereditary relationship can be traced, but there is no reliable confirmation of this fact.

Classification of types of brain tumors

1. Tumors of the brain. Occurs in 90% of cases.
2. Tumors of the spinal cord. The frequency of their diagnosis is 10%.

In relation to the brain:

1. Intracerebral. They originate from the cells of the substance of the brain.
2. Extracerebral. They can develop from the meninges, bone structures of the skull, cranial nerves.

In relation to the spinal cord:

1. Intramedullary - located in the substance of the spinal cord.
2. Extramedullary - located outside the spinal cord in the spinal canal.

Benign brain tumors do not have a direct destructive effect on the substance of the brain and on the body as a whole. But the features of the physiology of both the brain and the spinal cord are such that they are located in a closed space formed, respectively, by the bones of the skull and spine. Therefore, even a benign tumor of the head causes compression of the brain, the death of its cells, the development of appropriate symptoms, up to death.

A malignant brain tumor, in addition to the squeezing effect, has a toxic effect on the brain and the human body. Destroys neurons, sprouting in them. Metastasizes to other organs and tissues, forming secondary foci.

Features of the clinical picture in different types of tumors

All symptoms are divided into three groups:

1. Cerebral symptoms.
2. local symptoms.
3. Remote symptoms.

The first group includes signs caused by the development of intracranial hypertension due to an increase in tissue volume (this process is called "plus tissue"):

1. Specific headache - worse in the morning, has the character of aching, arching. Patients report a feeling of "heavy head".
2. Nausea of ​​varying severity, up to vomiting.
3. In severe cases, depression of consciousness is observed.

Symptoms of the second group - depend on the location of the tumor, are caused by compression or destruction of the substance of the brain. The third group includes signs caused by the dislocation of brain structures when the tumor reaches a large size. External manifestations will be observed not in the place of localization of the neoplasm, but in the place of displacement of the brain.

Clinical symptoms of a malignant brain tumor, depending on its location:

1. Frontal lobe. The defeat of this department leads to personality disorders, changes in behavior, lack of adequate critical perception of one's condition. Speech and movement disorders may develop.
2. The temporal share. When the process is localized in this area, “paroxysms of sensations” may develop. There are hallucinations of a different nature - taste, visual, auditory, emotional. With an extensive lesion, movement disorders, speech impairment are observed. hearing, memory, writing.
3. Parietal lobe. Since this area is responsible for all types of sensitivity and the sensation of the position of the body in space, sensitivity disorders will be observed when it is damaged. There may be sudden attacks of pain, fever or chills, a feeling of "cotton limbs". Violated coordination and balance.
4. Occipital lobe. There is a visual impairment according to the type of loss of visual fields, flickering flies, changes in color perception.
5. The ventricles of the brain. With their defeat, intracranial hypertension quickly develops with the appearance of cerebral symptoms.
6. Turkish saddle. Since the pituitary gland, which is responsible for the endocrine balance of the body, is located here, various hormonal disorders develop when this area is affected.
7. Spinal cord. In this case, there is a symptomatology due to irritation of the nerve roots - a pain syndrome, depending on the localization of the pathological process.

Interesting! Signs of dysfunction of the roots - lack of sensitivity in the area innervated by the affected segment. A benign tumor of the spinal cord causes its compression and dysfunction of organs located below the site of compression.

Methods for diagnosing and treating tumors

The diagnosis is made on the basis of data from a comprehensive examination of the patient. Of no small importance are the anamnesis of the disease and the features of the clinical picture. Imaging techniques are used to clarify the location and extent of the lesion. Laboratory diagnostics is not of great importance in making a diagnosis and is used only to detect secondary pathologies caused by a tumor.

1. MRI with contrast. The most optimal method that gives the most informative result. Allows you to clarify the localization of the tumor, its relation to the functional areas of the brain, the degree of damage to the medulla.
2. According to the indications, angiography, craniography, and a study of the electrical activity of the brain are used.

Removal of a benign tumor - surgical treatment is used to completely eliminate the manifestations of the disease. The only difficulty may be the location of the tumor in places where surgical intervention can lead to damage to the nerve or vessel.

Removal of a malignant tumor is technically more difficult, since it requires resection not only of visually damaged tissue, but also of apparently healthy tissue around the tumor. This technique is called ablastika, and is aimed at the maximum removal of tumor cells to prevent recurrence.

Forecast for life

The course of a malignant neoplasm is always more severe, and the chances of recovery are low. This is due to the double action of the tumor - local compression of the substance of the brain and the development of an intoxication syndrome that affects the entire body. A benign brain tumor - the prognosis in this case is more favorable. Surgical treatment allows you to completely get rid of the disease.

How to distinguish a benign tumor from a malignant one

Cancer cells are violators of all the rules of cell division. A single atypical cell among millions of decent brothers can lead to the development of a cancerous tumor.

The sequence of processes occurring in the body that lead to cancer are complex and variable. A combination of genetic, environmental and lifestyle factors can turn a normal cell into a pathological one.

What is the mechanism of tumor formation?

Our body is a unique system that maintains a balance between new and old cells. Our body is made up of countless cells. They differ in structure and function. However, regardless of whether this cell is heart or blood, it matures from its earlier predecessors. All cells are programmed to die on time. Their death is carefully controlled by the whole organism. Cell death is called apoptosis.

Division, maturation, and apoptosis are essential conditions for cell life. The accumulation of tumor cells occurs for several reasons: due to uncontrolled division, due to the impossibility of cells to mature and turn into their highly professional descendants (they simply remain at the development stage), and the impossibility of dying in time.

Tumors are clones. Tumor cells originate from one and recreate copies of the original cell. Damage to genes leads to disruption of division, maturation, and programmed death. When the body's defense system fails, the damaged cell survives and forms many clones.

Cancer cells not only violate the rules of division, but also do not respond to all sorts of stop signals coming from our body. For example, breast cancer cells grow without estrogen, which is the normal growth condition. Most cells can report that they are squeezed by other cells, but cancer cells ignore this signal and continue to multiply.

Tumors are such a diverse phenomenon that it is sometimes difficult to classify and divide them into groups. The causes of occurrence, the mechanism of growth, location and distribution determine the type of tumor. In this regard, tumors are divided into benign and malignant.

What is the difference between benign and malignant tumors?

To benign doctors include neoplasms that do not carry a big threat and have a favorable prognosis for life. Such tumors grow slowly, they lack the ability to relapse and metastasize, they do not grow into neighboring tissues and organs. Often, benign tumors stop growing and begin to develop in the opposite direction.

However, all this does not mean that such tumors are harmless. For example, a benign tumor of the endocrine gland can cause hormonal imbalances, and in the small intestine, if large, it can compress the intestinal loops, causing intestinal obstruction.

Malignant tumors, as the name implies, are extremely dangerous for the body. They are characterized by rapid growth, the ability to spread throughout the body, giving metastases, and also to grow into neighboring tissues and organs. A malignant tumor can completely remove the organs and vital systems of the human body from normal functioning.

A malignant tumor does not always have a clear difference from a benign one. In this regard, separate groups of neoplasms are distinguished: locally destructive and potentially malignant. The first have all the features of malignant, except for metastasis (basal cell skin cancer, desmoid fibroma). Potentially malignant tumors superficially resemble benign ones, but can metastasize (carcinoid, giant cell tumor of bone).

How to determine a cancerous tumor?

Unfortunately, none of us is immune from the appearance of a malignant tumor. But if you recognize cancer at an early stage, you can successfully recover from the disease. Next, we will talk about the symptoms of this disease - if you find any of them in yourself or your loved ones, you will need to check with a good doctor. Diagnosis of cancer should be carried out by a professional doctor who will prescribe competent treatment.

Cancer Symptoms

The following common signs of cancer are distinguished: swelling, coughing, hoarseness and shortness of breath, bleeding, causeless weight loss, negative changes in the digestive tract and moles. Let's consider each of them in a little more detail.

1. Small swellings and lumps on the body are often harmless, but not always. If you notice an abnormal seal on any part of the body, it is better to see a doctor just in case. For example, breast cancer is diagnosed precisely by the formation of bumps and seals in the mammary gland. It is recommended that every woman periodically feel her breasts to check her condition. In case of detection of abnormal seals, it is imperative to contact a mammologist.
2. If a person develops lung cancer, they will suffer from coughing, hoarseness, and shortness of breath. These same signs may indicate inflammation and infection, but in any case, you need to see a doctor. It is especially important to pay attention to these symptoms if shortness of breath and cough do not go away within two weeks. Also look for blood in the sputum.
3. Hoarseness may indicate cancer of the larynx.
4. Any bleeding for no apparent reason will indicate a malfunction of the internal organs, including cancer.
5. It is important to pay attention to changes in the functioning of the digestive tract, if they are not caused by excitement, changes in diet and diet, or medication. The presence of cancer can be indicated by the frequent occurrence of constipation or diarrhea for no apparent reason, pain in the abdomen and intestines. A feeling of incomplete bowel cleansing after a stool can also indicate the development of the disease.
6. Weight loss without objective reasons can also indicate the development of the disease. If you've lost a lot of weight in the past few months without experiencing much stress, dieting, or vigorous exercise, you should definitely see your doctor.
7. Pay attention to your moles. Melanoma is considered one of the types of cancer - it can form on an existing mole or appear as a new large one. You need to contact a specialist if you have the following symptoms:
   • Asymmetrical moles with uneven edges (usually symmetrical and even);
   • Non-standard color (the usual mole is brown, melanoma may have an admixture of black, red, pink, bluish and white);
   • Large moles (melanomas larger than 7 mm);
   • If the mole is covered with a crust, itches and bleeds.

If strange spots appear on the skin that do not go away for a long time, be sure to consult a doctor. In no case should you remove moles on your own, as well as damage them - this can lead to the development of a tumor! If you have large and bulging moles, try not to touch them, and if this happens and blood starts to flow, be sure to see a doctor. Any mole with careless handling can lead to the development of the disease. Especially large ones are recommended to be removed by a specialist - it is fast and safe.

If you have any of the above symptoms, do not hesitate to visit a specialist. The doctor will assess your health condition and, if necessary, send you for procedures and examinations, after which he will prescribe the appropriate treatment. If cancer is suspected, you will be sent for a tomography, a biopsy, and a specialized doctor will be advised.

People who are at risk

1. Those who are subject to long and harmful influences. This includes contact with carcinogens, toxic dyes and radiation. Smokers are also at risk.
2. Hereditary predisposition to cancer. In this sense, certain types of cancer can be distinguished, for example, cancer of the genital organs or intestines. If your blood relatives suffered from such diseases, then you are several times more likely to have the disease. If at least two or three relatives had cancer, you should consult a genetic oncologist.
3. Those who suffer from precancerous diseases or have chronic injuries or inflammation. Precancerous diseases are those that can lead to cancer. These include mastopathy, intestinal polyposis, cirrhosis of the liver.

Those who are at risk need to be examined once or twice a year in a specialized clinic.

A malignant tumor is a pathological process accompanied by uncontrolled, uncontrolled reproduction of cells that have acquired new properties and are capable of unlimited division. Oncological pathology in terms of morbidity and mortality has long taken second place, second only to diseases of the heart and blood vessels, but the fear that causes cancer in the vast majority of people is disproportionately higher than the fear of diseases of all other organs.

As you know, neoplasms are benign and malignant. Features of the structure and functioning of cells determine the behavior of the tumor and the prognosis for the patient. At the diagnostic stage, the most important thing is to establish the malignant potential of the cells, which will predetermine the further actions of the doctor.

Oncological diseases include not only malignant tumors. This category also includes completely benign processes, which are nevertheless dealt with by oncologists.

Among malignant neoplasms, cancers (epithelial neoplasias) are the most common.

Among benign neoplasms, the most common are.

Properties of malignant tumors

In order to understand the essence of tumor growth, it is necessary to consider the basic properties of the cells that make up the neoplasm, which allow the tumor to grow independently of the whole organism.

Malignant neoplasms are represented by cancer, sarcomas, tumors from the nervous and melanin-forming tissue, teratomas.

carcinoma (cancer) on the example of the kidney

A special kind of tumors are those that appear even in fetal development in violation of the displacement of embryonic tissues. Teratomas are both benign and malignant.

Features of malignant tumors, allowing them to exist independently of the organism, subordinating it to their needs and poisoning it with waste products, boil down to:

• autonomy;
• Cellular and tissue atypia;
• Uncontrolled reproduction of cells, their unlimited growth;
• Opportunities .

The emergence of the ability to autonomous, independent existence - the first change that occurs in cells and tissues on the way to tumor formation. This property is genetically predetermined by mutation of the corresponding genes responsible for the cell cycle. A healthy cell has a limit in the number of its divisions and sooner or later stops reproducing, unlike a tumor cell, which does not obey any signals from the body, divides continuously and for an arbitrarily long time. If a tumor cell is placed in favorable conditions, then it will divide for years and decades, giving offspring in the form of the same defective cells. In fact, the tumor cell is immortal and is able to exist in changing conditions, adapting to them.

The second most important sign of a tumor is atypia, which can be detected already at the stage of precancer. In a formed tumor, atypism can be expressed to such an extent that it is no longer possible to establish the nature and origin of the cells. Atypia is new, different from the norm, properties of cells that affect their structure, functioning, and metabolic characteristics.

Benign tumors present with tissue atypia, which consists in a violation of the ratio between the volume of cells and the surrounding stroma, while the tumor cells are as close as possible to normal in structure. Malignant neoplasms, in addition to tissue, also have cellular atypia, when cells that have undergone neoplastic transformation differ significantly from normal ones, acquire or lose the ability to certain functions, the synthesis of enzymes, hormones, etc.

different variants of tissue and cellular atypia on the example of cervical cancer

The properties of a malignant tumor are constantly changing, its cells acquire new features, but often in the direction of greater malignancy. Changes in the properties of tumor tissue reflect its adaptation to existence in a variety of conditions, whether it be the surface of the skin or the gastric mucosa.

The most important ability that distinguishes a malignant tumor from a benign one is metastasis. Normal cells of healthy tissues and elements of benign tumors close to them are closely interconnected through intercellular contacts, therefore, spontaneous separation of cells from tissue and their migration are impossible (of course, except for organs where this property is a necessity - bone marrow, for example). Malignant cells lose surface proteins responsible for intercellular communications, break away from the main tumor, penetrate into the vessels and spread to other organs, spread over the surface of the serous integuments. This phenomenon is called metastasis.

metastasis (the spread of a malignant process throughout the body) is characteristic only of malignant tumors

If metastasis (spread) of the tumor occurs through the blood vessels, then secondary tumor accumulations can be found in the internal organs - the liver, lungs, bone marrow, etc. In the case of metastasis through the lymphatic vessels, the lesion will affect the lymph nodes that collect lymph from the site of the primary localization of neoplasia. In advanced cases of the disease, metastases can be detected at a considerable distance from the tumor. At this stage, the prognosis is poor, and patients can only be offered palliative care to alleviate the condition.

An important property of a malignant tumor, which distinguishes it from a benign process, is the ability to grow (invasion) into adjacent tissues, damaging and destroying them. If a benign neoplasm, as it were, pushes back tissues, compresses them, can cause atrophy, but does not destroy it, then a malignant tumor, releasing various biologically active substances, toxic metabolic products, enzymes, penetrates into the structures surrounding it, causing their damage and death. Metastasis is also associated with the ability for invasive growth, and such behavior often does not allow complete removal of neoplasia without violating the integrity of the organ.

Oncological disease is not only the presence of a more or less localized tumor process. Always with the malignant nature of the lesion, there is also overall influence neoplasia on the body which gets worse from stage to stage. Among the general symptoms, the most well-known and characteristic are weight loss, severe weakness and fatigue, fever, which is difficult to explain at the very initial stages of the disease. As the disease progresses, cancerous cachexia develops with severe exhaustion and dysfunction of vital organs.

Properties of benign tumors

A benign tumor is also in the field of view of oncology, but the risk and prognosis for it is incommensurably better than for a malignant one, and in the vast majority of cases, timely treatment allows you to completely and permanently get rid of it.

A benign neoplasm consists of cells developed to such an extent that its source can be unmistakably determined. The uncontrolled and excessive reproduction of the cellular elements of a benign tumor is combined with their high differentiation and almost complete correspondence to the structures of healthy tissue, therefore, in this case, it is customary to speak only of tissue atypia, but not of cellular atypia.

About the tumor nature of benign neoplasms they say:

• Inadequate, excessive cell reproduction;
• The presence of tissue atypia;
• Possibility of recurrence.

A benign tumor does not metastasize, since its cells are firmly interconnected, do not grow into neighboring tissues and, accordingly, do not destroy them. As a rule, there is no general effect on the body, the only exceptions are formations that produce hormones or other biologically active substances. Local influence consists in pushing healthy tissues away, squeezing them and atrophy, the severity of which depends on the location and size of the neoplasia. Benign processes are characterized by slow growth and a low probability of recurrence.

differences between benign (A) and malignant (B) tumors

Of course, benign neoplasms do not inspire such fear as cancer, but still they can be dangerous. So, there is almost always a risk that can occur at any time, whether it be a year or decades after the onset of the disease. The most dangerous in this regard are urinary tract papillomas, certain types of nevi, adenomas and adenomatous polyps of the gastrointestinal tract. At the same time, some tumors, for example, a lipoma, consisting of adipose tissue, are not capable of malignancy and deliver only a cosmetic defect or have a local effect due to their size or location.

Varieties of tumors

To systematize information about known tumors, unify approaches to diagnosis and therapy, classifications of neoplasms have been developed that take into account their morphological features and behavior in the body.

The main feature that allows dividing tumors into groups is the structure and source. Both benign and malignant neoplasia are of epithelial origin, may consist of connective tissue structures, muscles, bone tissue, etc.

Epithelial malignant tumors united by the concept of "cancer", which is glandular (adenocarcinoma) and derived from MPE (squamous cell carcinoma). Each variety has several levels of cell differentiation (highly, moderately, poorly differentiated tumors), which predetermines the aggressiveness and course of the disease.

Benign epithelial neoplasia include papillomas originating from squamous or transitional epithelium and adenomas consisting of glandular tissue.

Adenomas, adenocarcinomas, papillomas do not have organ differences and are built stereotypically in different localizations. There are forms of tumors that are characteristic only of specific organs or tissues, such as breast fibroadenoma or renal cell carcinoma.

Much more diverse, in contrast to epithelial neoplasms, are tumors originating from the so-called mesenchyme. This group includes:

• Connective tissue formations (fibroma, fibrosarcoma);
• Fatty neoplasia (, liposarcoma, brown fat tumors);
• Muscle tumors (rhabdo- and leiomyomas, myosarcomas);
• Bone neoplasms (, osteosarcomas);
• Vascular neoplasias (hemangiomas, vascular sarcomas).

The appearance of the tumor is very different: in the form of a limited node, cauliflower, fungus, in the form of structureless growths, ulcers, etc. The surface is smooth, rough, bumpy, papillary. In malignant formations, secondary changes are often found, reflecting the disturbed metabolism of cells with their ingrowth into the surrounding structures: hemorrhages, necrosis, suppuration, the formation of mucus, cysts.

Microscopically, any tumor consists of a cellular component (parenchyma) and stroma, which performs a supporting and nourishing role. The higher the degree of differentiation of the neoplasm, the more ordered its structure will be. In poorly differentiated (highly malignant) stromal tumors, there may be a minimal amount, and the bulk of the formation will be malignant cells.

Neoplasms of very different localization are widespread everywhere, in all geographical zones, they spare neither children nor the elderly. Having appeared in the body, the tumor skillfully “leaves” the immune response and defense systems aimed at removing everything foreign. The ability to adapt to different conditions, changing the structure of cells and their antigenic properties, allows the neoplasm to exist independently, "taking away" everything necessary from the body and returning the products of its metabolism. Having arisen once, cancer completely subjugates the work of many systems and organs, disabling them with its vital activity.

Scientists around the world are constantly struggling with the problem of tumors, looking for new ways to diagnose and treat the disease, identify risk factors, and establish the genetic mechanisms of cancer. It should be noted that progress in this matter, albeit slowly, is happening.

Today, many tumors, even malignant ones, can be successfully treated. The development of surgical techniques, a wide range of modern anticancer drugs, new radiation techniques allow many patients to get rid of the tumor, but the search for means to combat metastasis remains a priority for research.

The ability to spread throughout the body makes a malignant tumor virtually invulnerable, and all available methods of treatment are ineffective in the presence of secondary tumor conglomerates. I would like to hope that this mystery of the tumor will be solved in the near future, and the efforts of scientists will lead to the emergence of a truly effective therapy.

Diseases

In the human body, cells are constantly dividing. For various reasons, this process can be disrupted, resulting in their excessive formation on some parts of the body. In these places, tumors appear, which are usually divided into malignant and benign. The classification depends on many factors, and sometimes it is not possible to draw a clear line.

How to distinguish a benign tumor from a malignant one?

Formations, first of all, are usually divided into the composition of the new tissue. It may correspond to the organ on which the pathology has appeared, or it may consist of completely different types of cells. The principal differences between benign and malignant tumors are as follows:

• Growth rate. Malignant formations rapidly increase in size, the process is very difficult to control.
• The presence of metastases. Benign formations never give them.
• The appearance of relapses after treatment. These complications are often observed in cases of malignant tumors.
• Influence on the general condition. Benign formations do not bring negative sensations, they are often noticed by chance.

Tumors that do not cause concern are composed of surrounding tissue. Malignant formations differ sharply in their structure. Sometimes the cells that make them up are so unusual that it's impossible to tell what they're made of.

To understand how a benign tumor differs from a malignant one, you need to get a little familiar with the growth of the human body. A cell goes through four stages during its lifetime. The first three prepare it for division, which occurs under normal conditions. The body controls each stage, and in case of any deviations, it stops the process until the anomalies are corrected. But sometimes the protective functions do not cope with their task, which leads to tumors. The reasons for this may be:

• viral and fungal infections;
• decreased immunity due to chronic diseases;
• genetic predisposition.

With the appearance of any tumor there is a danger. It is almost impossible to independently determine its type, therefore, in order to reduce the risk of serious consequences, it is necessary to use medical help. This should be done even if the neoplasm does not cause inconvenience and does not cause concern.

Which doctor should I go to?

The choice of a specialist depends entirely on the location of the tumor and the symptoms that appear. You need to understand that only a doctor can determine which tumor, benign and malignant, the difference in their progression. Several doctors deal with neoplasms, and it is not always clear who to turn to. In any case, you can help:

Having determined the type of tumor, the doctor will begin treatment or refer the patient to the right specialist. It can be a dermatologist, endocrinologist, andrologist, orthopedist and others. In cases with benign tumors, the prognosis is generally positive. Malignant tumors may require serious and long-term treatment.

The formation of tumors in the human body is possible at any age. There are many reasons for this. What tumors are, where they come from and how to deal with them, scientists do not fully know. However, there is an understanding that tumors are benign and malignant. They find different consequences and symptoms, the treatments also differ from each other.

A tumor is a process of tissue change in which the number of cells increases at a rapid rate. Tumors are divided into two groups - benign and malignant.

A benign tumor is a neoplasm, the cause is a failure in the process of cell division. This tumor is characterized by slow growth. It is well treated by surgical removal and in most cases does not lead to relapse. Does not spread to nearby organs, does not metastasize.

A benign tumor can occur in any organ. In medicine, the division of diseases into a number of types is used:

• Adenoma, or glandular tumor. Formed in organs with glandular tissue. For example, in the mucous membrane of the uterus and in the rectum, mammary or thyroid gland, etc.
• Atheroma. Localization of such a tumor is possible in any area of ​​the body where hair grows (head, groin area, lower face and neck, back). The reason is the blockage of the duct of the sebaceous glands.
• Cyst. An abnormal cavity formed in organs or tissues. There is probably liquid inside.
• Lymphangioma. Formation from lymphatic vessels. It usually develops in the womb. Localization anywhere. The neck, subcutaneous tissue is usually affected. Cases of occurrence in the liver and kidneys are possible, but rarely.
• Lipoma, or wen. Neoplasm in the subcutaneous connective tissues, probably spreading deeper. It is often localized in the area of ​​the shoulders and outer thighs, where there is relatively little adipose tissue.

• Meningioma. Tumor of the tissues surrounding the brain. Areas of localization: at the base of the brain, above it and between the hemispheres.
• Myoma. A neoplasm whose cells grow from immature muscle tissue.
• Neuroma. Formed from nerve cells. The reason is more often traumatic, ie. in the area of ​​​​the scar, the nerve is compacted.
• Papilloma. Formations on the mucous surface or over the skin caused by papillomavirus. Visually, it has the shape of a papilla protruding above the affected surface.
• Osteoma. A tumor formed in the bone tissue.
• Fibroma. Neoplasm of connective cells. As a rule, it sticks out above the skin and has a light pink tint.

A malignant tumor, or cancer, is characterized by uncontrolled cell division and poses a threat to human life. Malignant cells are easily detached from the tumor and distributed throughout the body through the blood vessels. When it enters the body, a new formation appears. This is how metastasis occurs. In addition, cancer cells are capable of destroying nearby tissues. After completion of therapy, a malignant tumor may reappear, i.e. recur.

Cancer neoplasms are usually divided into groups depending on the cells from which they are formed. Examples:

• Glioma. Malignant tumor of the central nervous system. It affects the cells of the spinal cord and brain.
• Carcinoma. Actually, cancer develops from the tissues of any organs, as well as mucous membranes and skin.
• Leukemia, or leukemia. Oncology that affects the cells of the hematopoietic system.

• Lymphoma. Cancer of the tissues of the lymphatic system.
• Melanoma. A malignant neoplasm on the skin originating from the cells of age spots, mainly in places where the synthesis of melanin pigment is concentrated.
• Sarcoma. Occurs rarely. It is formed from cells of soft or bone tissues. Soft tissues include tendons, muscles, and fats.
• Teratoma. It affects the primary germ cells, resulting in a tumor of the ovaries in women or testicles in men.

Symptoms of tumor diseases

Benign neoplasms in the first stages of growth are manifested in the form of general weakness and decreased appetite. As the disease progresses, more “deeper” symptoms are added:

• pain;
• bleeding;
• increased body temperature;
• sudden weight loss;
• feeling of internal pressure on the organs;
• nausea.

When a neoplasm appears on the skin or in an area accessible to palpation, the presence is easy to determine upon examination.

It is no secret that benign tumors can degenerate into malignant ones. This process is called malignancy.

The process of malignancy usually takes place when the disease is neglected, then more serious and painful symptoms are possible:

• Strange discharge or bleeding. The presence of blood in saliva, feces or urinary masses, bloody uterine discharge and others indicate the possibility of developing cancer of certain organs.
• Bowel or bladder disorders.
• The appearance of bumps or seals on various parts of the body.
• Education on the skin. For example, ulcers, the appearance of warts, changes in moles and birthmarks.
• Throat changes. For example, a constant cough, wheezing in the voice, unpleasant or painful sensations during swallowing.

These symptoms can be the cause of oncology, but many other diseases are not excluded. Therefore, with any changes in the state of health, it is necessary to consult a doctor and undergo an examination. You may need to be tested for cancer cells.

Signs that distinguish a benign tumor from a malignant one

A benign formation differs from a malignant tumor in the process of development and the period of rehabilitation, namely:

1. Growth rate. Benign cells grow much slower than cancer cells. However, as with any statistics, there are exceptions. Selected "bad" formations also increase extremely slowly.
2. Stickiness. In benign tumors, cells stick to each other by producing sticky chemicals. Malignant cells do not secrete such substances, so the tumor is more fragile, as a result, some of the cells can fall off and spread throughout the body with the bloodstream. The result is the growth of metastases.
3. The ability to infect nearby organs. Benign cells in the process of growth displace nearby organs and tissues, but do not penetrate into them. While cancer cells have this ability.
4. Methods of treatment. Cancer treatment often involves radiation and chemotherapy prior to surgical removal. And the treatment of benign tumors allows you to operate immediately.
5. Relapses. Recurrence of malignant tumors is common. And at the same time appears in another organ of the body. Benign recurrences are extremely rare, but if this happens, then a new lesion appears in the same place or very close.
6. Mortality. Unlike a benign, a “bad” tumor has a high mortality rate and exceeds it tenfold.

Commonality between cancer and benign diseases

Despite the big difference between the phenomena, there are common signs:

• Both “bad” and “good” education are capable of rapid growth.
• Both types of tumors are life-threatening. A malignant one always carries this threat, and a benign one, when it appears and grows in a tight space, for example, in the head, producing pressure and causing irreparable damage to neighboring tissues and structures.
• The likelihood of recurrence of the disease. In both cases, a relapse is likely due to the affected cells remaining after removal.

Etiology

To benign formations in the body leads to a failure at the cellular level. A cell in a healthy body lives for 42 hours. At this time, it appears, grows and dies. Instead, a new one appears, following the same path. If for some reason the cell does not die and continues to grow, then a tumor forms in this place. These reasons include:

• Harmful effects of UV radiation, poisonous vapors and radiation.
• Excessive consumption of unhealthy foods and drinks: alcohol, carbonated drinks, fast food and processed foods.
• Failures in the mode: sleep disturbances, overwork.
• Use of drugs and tobacco products.
• Hormonal imbalances and weakening of the immune system.
• Mechanical damage: bruises, sprains, dislocations and fractures.

Malignant neoplasms develop independently or during the degeneration of benign tumors. Scientists have proven that up to 80% of oncology cases depend on the influence of external factors:

• Influence of carcinogens of chemical or physical origin. Chemicals affect the body when they enter with unhealthy food or at the time of inhalation of hazardous fumes, for example, in cases of work in hazardous industries. The body receives physical carcinogens under the influence of radiation: ionizing or UV rays.
• Genetics. Scientists link the tendency to the formation of cancer with heredity. For example, close relatives have cancer - the probability of the disease in the representatives of the next generation increases three times.
• Oncoviruses. A number of viruses, together with other physical factors, provoke the development of malignant neoplasms.

Growth stages of benign cells

In medicine, three stages of development of neoplasms of a benign nature are defined:

1. Initiation. At this stage, the detection of the disease is extremely rare, because. changes occur at the DNA level and do not entail a deterioration in well-being or other symptoms. The mutation process affects two genes, one of which is responsible for the lifespan of the cell, and the second for its reproduction. When one of the genes is mutated, a benign formation is formed.
2. Promotion. Here there is an active reproduction of cells that have undergone a mutation. Tumor promoters are responsible for the process. The stage lasts for years without showing symptoms, making it difficult to diagnose the disease, leading to the next stage.
3. Progression. This stage is critical for the patient. The growth rate of altered cells increases. As a rule, a benign formation does not pose a threat of death, but affects the organs located in the neighborhood, by squeezing and leading to disruption of the body. Progression aids in making a diagnosis, as the symptoms manifested at the described stage lead the patient to examination.

At the stage of progression, there is a risk of malignancy. The situation is facilitated by external factors that provoke altered cells to rapid growth.

Stages of cancer development

It is customary to distinguish four stages in the development of cancer:

1. The first stage of development corresponds to precise localization. The formation is located in a specific area and does not grow into neighboring tissues.
2. The tumor continues to grow and becomes large, but still remains within the original area. Cases of the appearance of metastases are observed exclusively in the lymph nodes located nearby.
3. The third stage is characterized by the launch of the processes of decay and germination into the walls of the organ. The presence of metastases in neighboring lymph nodes is recorded.
4. The fourth stage corresponds to germination in neighboring tissues and organs. Metastases appear in other organs.

Differences in diagnosis

Differences between malignant and benign tumors are observed not only in symptoms and development, but also in diagnosis.

As a rule, a benign formation does not differ in symptoms that indicate the need for a visit to the doctor. It is usually diagnosed during an examination associated with other complaints or prophylaxis.

Diagnostic methods in such cases depend on where the formation is located and what kind it has. It is more often found during examination on ultrasound and X-ray machines. Further, when collecting the necessary tests, the doctor determines how dangerous the tumor is.

Oncology diagnostics

If, during the examination and history taking, the symptoms that the patient complains about lead to the suspicion of an oncological process, the therapist gives a referral for an examination to the oncology center.

Oncologists use a number of diagnostic methods:

1. Collection of analyses. Blood is taken from the patient for general and biochemical analysis. A table of values ​​showing deviations from the norm helps to determine the condition of the organs. If a neoplasm is detected, biological material is additionally taken from the affected area for a biopsy. It is the most accurate tool to help determine the type of mutation cells and check the degree of their malignancy. The results obtained as a result help to predict the further development of the tumor and choose the most appropriate treatment.
2. Devices for diagnostics. They are selected according to the location of the suspected neoplasm.

CT scan. Diagnostic method based on x-rays. Informative, but not always safe, because. the patient receives some dose of radiation. Therefore, it is often not possible to use this method. On CT, an examination of the lungs, kidneys, joints, brain, abdominal cavity and pelvic organs is performed, if a cyst (cavitary formation) is suspected.

Colonoscopy, bronchoscopy. These effective endoscopic devices make it possible to detect a tumor at an early stage of development. A colonoscopy examines the rectum. Bronchoscopy allows you to find out the condition of the trachea and bronchi.

MRI. Determines oncology in the areas: brain, joints, spine, hip joints, chest. The method is effective and safe. The main advantage and difference in comparison with CT is that there is no exposure to the body, and you can freely schedule an examination as many times as needed.

Mammography is a way to confirm or rule out breast cancer. The method is safe and does not pose a risk of worsening the situation. Contraindications include only pregnancy and lactation. On mammography, the presence of dark areas tells the radiologist about changes in the structure of the mammary glands.

X-ray. X-ray examination reveals the presence of a tumor in the kidneys, liver, bladder, lungs.

ultrasound. An informative method that examines many organs other than hollow ones, such as the intestines or lungs.

Dangers associated with the development of tumors

Despite the fact that benign growths are considered safe, the disease should not be underestimated. As mentioned above, under the influence of harmful factors, tumors degenerate into cancer. Also, neoplasms of a non-hazardous nature are able to grow, affecting other organs, which leads to disruption of the body.

Therefore, in order to avoid meeting with such diseases, it is necessary at least to help the body and exclude from everyday habits:

• destructive habits;
• unhealthy diet;
• sedentary lifestyle.

The human body is able to adapt to starvation. In the process of carbohydrate deficiency, ketosis develops, which promotes the renewal of affected cells. Therefore, the keto diet is prescribed in the treatment complex.
