There are treatments for all patients with an adult brain tumor. To take out the cancer from the brain, a doctor will cut a part of the bone from the skull to get to the brain. This operation is called a craniotomy. After the doctor removes the cancer, the bone will be put back or a piece of metal or fabric will be used to cover the opening in the skull.
Chemotherapy uses drugs to kill cancer cells.
Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells throughout the body. Biological therapy tries to get the body to fight cancer. It uses materials made by the body or made in a laboratory to boost, direct, or restore the body's natural defenses against disease. Biological therapy is sometimes called biological response modifier therapy or immunotherapy.
