Brain cancer: symptoms, causes

Many people have heard of the terrible diagnosis of cancer, but not all of them understand what exactly is meant by this name.

Cancer (neoplasms, malignant tumors) is a process in which cells of various tissues for different reasons cease to share normally, begin to actively, but uncontrollably, aggressively expand. Spreading first disturbs the functioning of the diseased organ, leads to its alteration, and then disrupts the functioning of the organism as a whole.

Cancerous tumors have many varieties. So the sarcoma is caused by the growth of connective tissue, lymphoma is a modification of the lymph nodes, carcinoma is the germination of epithelial tissues into internal organs.

The causes of the appearance of cancer to date are not exactly defined. It is known that among the risk factors are heredity, unhealthy lifestyle, obesity, poor ecology, radiation or chemical pollution, Some doctors believe that the cause of cancers can be fungi or bacteria.

It is well known that the main cause of death from cancer are metastases, i.e. Overgrown cells that hit other organs and disturbed their work.

About 15% of all deaths on Earth are the result of the appearance of malignant neoplasms.

Not the last place among the widespread neoplasms is the cancer of the brain.

In this disease, malignant cells begin to form in the brain, causing brain cancer. Symptoms usually depend on the place of origin of the tumor, but there are a number of signs that raise suspicions about the development of the tumor.

The disease begins to manifest itself with strong, persistent headaches, general weakness, lack of appetite, weight loss. Somewhat later, nausea, vomiting, alertness, nervousness may appear.

Since such manifestations are inherent in many diseases, it is very difficult to diagnose at this stage. If the diagnosis is not made, and the treatment is not started, there may be a violation of the sensitivity of the skin, an inability to determine its position in space. Patients do not feel cold or warm, can not determine where the top, where the bottom. Often there are epileptic seizures or convulsions, impaired coordination, psychomotor abnormalities.

At this stage, help diagnose brain cancer symptoms characterized by gait changes, inability to control movements with closed eyes.

Somewhat later, there are manifestations that directly suspect brain cancer. Symptoms depend on the location of the tumor. So the location of the tumor in speech centers will disrupt speech, and its occurrence in the departments responsible for hearing can cause noise in the ears, deafness, auditory hallucinations. If the pituitary gland or hypothalamus is affected, the hormonal balance of the body can be destroyed.

In order to prevent the emergence of a terrible disease, many countries in the world introduced a special program that obliges all citizens to undergo a medical examination every year. In Russia, doctors are most often treated not at the beginning of the illness, but when the disease has already caused much harm.

Treatment of tumors can be divided into three types: surgical removal of the brain tumor, chemotherapy, radiotherapy and radiotherapy.

Brain cancer , the symptoms of which indicate a small tumor size, can be cured with the Gamma Knife technology. This newest direction of radiosurgery makes it possible to successfully combat malignant small tumors by means of a stereotaxic irradiation device.

In the case of a strong tumor growth, a classical surgical procedure is performed to remove it.
