Avastin (generic: bevacizumab) is a prescription medication used to treat symptoms of Glioblastoma (GBM), a fast growing brain tumor. It is also used to treat symptoms of colon cancer, colorectal cancer, lung cancer, or renal cell cancer (a type of cancer that begins in the kidney). Avastin belongs to a group of drugs called antiangiogenic agents, which stops blood vessels that feed tumors from forming.

This medication comes in a liquid form and is injected intravenously (into a vein) by your doctor or healthcare provider. You will most likely receive an injection every 2 or 3 weeks.

Common side effects of Avastin include nosebleeds, headache, and high blood pressure.
