Today the doctors in our practice are faced with a huge number of types of brain tumors: benign and malignant. The tumor may initially develop in the brain or its development may start in other tissues and then switch on the brain(metastatic tumors).
Every year a growing number of diagnosed brain tumors. But the reasons for this rapid growth of cancer development is not yet known. Today the structure of the brain remains largely a mystery to us.
Brain tumor causes the following symptoms:
• nausea and vomiting that cannot be explained;
• loss of feeling or sensation in the leg or arm;
• speech disorders;
• problems with observance of equilibrium;
• difficulties in carrying out everyday activities;
• behavioral and personality changes;
• hormonal disorders;
• drowsiness, confusion, spoor, stun;
• cerebral coma.
Typically, the cell growth of primary brain tumors begins when normal cells are faced with mutations in DNA. Cells divide and grow at very high speed, not die even when their healthy brothers are killed. Develops the growth of abnormal cells, which, in consequence, form a tumor.
Primary brain tumors develop much less those in which the tumor process starts in some organ and then spreads to the brain. The classification of primary brain tumors is the type of tissue from which they originate. Here are some of them: Sanoma, glioblastoma or glioma, astrocytoma, ependymoma, medulloblastoma, ependymoblastoma, neuroblastoma, meningioma, pineoblastoma, oligodendroglioma etc.

Most often the emergence of primary brain cancer causes abnormal proliferation of glial cells. There are certain prerequisites for the development of this insidious disease. Often brain tumors are diagnosed in people working activities are associated with harmful production (Oil, steel, chemical and other). Neurosurgeons have noted a certain tendency in heredity, but to call this factor the direct cause as of yet. Experts also suggest that the development of brain cancer can result from exposure to radioactive radiation, viral infection, Smoking. The exact causes of brain cancer none of the scientists to identify so far failed.
