person could die. A malignant tumor is a tumor that could potentially invade and destroy important tissues and cells. They can also spread to other parts of the body (metastasize). Brain tumors can initially start in the brain. They can also spread to other parts of the body from the brain but this rarely happens. Some tumors may be worse than others. Tumor staging is used to determine the extent of cancer. The stage indicates if the cancer has spread and how far. The stages are listed below: T = Primary tumor size/extent T0: Primary tumor not present T1, T2, T3, T4 The higher the number, the larger the size/extent of the tumor. N = Regional lymph node involvement N0: No lymph node involvement N1, N2, N3 The higher the number, the more lymph node involvement. M = Distant metastasis M0: no metastasis M1: Metastasis present The cause of brain cancer is unknown. It is likely they are caused by many factors. Some of these factors are genetic damage, inheritance,
