There are several effective, non-surgical medical treatments available to manage brain tumors. First, chemotherapy uses drugs like temozolomide to stop tumor cells from growing. Second, targeted therapy uses medicines like bevacizumab to block the specific proteins or blood vessels that help tumors survive. Third, immunotherapy helps your body's own immune system recognize and fight the tumor. Additionally, supportive medications are used to keep you comfortable; these include corticosteroids (such as dexamethasone) to reduce brain swelling and anticonvulsants to prevent seizures. Your healthcare team will customize these options to provide the safest and most effective care for your specific situation.
