Brain Cancer (Neurological Cancers)

A neurological disease, brain cancer can grow aggressively and cause seizures, muscle weakness, behavioral changes and hearing loss. When abnormal cells form in the brain, they force out healthy ones and cause tumors to develop. These tumors often start in the brain or in nearby tissues, such as the outer covering of the brain called the meninges, the cranial nerves or the pituitary and pineal glands. Although the exact cause of brain cancer is unknown, your risk increases if you smoke cigarettes, have been exposed to radiation to the head, or have been exposed to certain chemicals. Cancerous tumors that spread can interfere with our central nervous system, which controls all of our bodys processes. Tumors that begin in the brain are much more rare than tumors that begin elsewhere and then spread to the brain. Cancers that start in the breast, colon, kidney or lungs commonly spread to the brain.
