The brain tumor consists of the abnormal growth of cells in the brain tissues of both benign and malignant types. It is necessary to distinguish between neoplasms that originate from the central nervous system, also called primary tumors, and those that arise from metastases that reach the brain.
THEThe first type is rarer and represents approximately 1.6% of all tumorsthe second derivative is more frequent. Most tumors are called primary gliomas and develop from the supporting cells of the central nervous system. It has often been found in juvenile forms of gliomas the presence of the mutation of the Idh genes, which is rarer in tumors of adults and the elderly.
There are no particular predispositions towards the onset of these tumors, the only certain link is that with high-dose radiation, while there is no evidence that electromagnetic fields cause tumors. I am there are also few cases of nervous system tumors within the same familythe genes that might cause a brain tumor to be inherited have not yet been identified.
There are some symptoms that represent small alarm bells that may recommend scheduling a visit to a specialist.
