Brain Cancer (Neurological Cancers)

Brain cancer and brain tumor are used interchangeably, but not all brain tumors are cancerous (malignant). Malignant brain tumors grow aggressively, overpowering healthy cells and destroying nearby brain tissues. Cancer that begins in the brain (primary brain cancer) is far less common than cancers that begin in other parts of the body. While cancer that starts in the lungs, breast, kidneys or other parts of the body may spread to the brain, primary brain cancer is less likely to spread outside the brain. Although the exact cause of this neurological disease is unknown, your risk increases if you smoke cigarettes, have been exposed to radiation to the head, or have been exposed to certain chemicals.
