When possible, surgery is performed to remove the entire tumor, or as much of the tumor as safely possible.
Radiation therapy is another common treatment. It uses radiation, such as high-energy x-rays, to kill cancer cells. External radiation therapy is a type of radiation that sends radiation towards the cancer using a machine outside the body. Internal radiation therapy uses radioactive substances that are sealed in wires, catheters, seeds, or needles, that are placed near or directly in the cancer. The stage of the cancer and the type will determine the type of radiation used.
Chemotherapies are drugs administered to cancer patients to stop cancer cell growth by preventing cell division or killing the cells. The drugs enter the patient's bloodstream when injected into a muscle or vein, or taken by mouth, and reach the cancer cells located throughout the body. When chemotherapy drugs are directly placed into an organ, into the spinal cord, or into the abdomen or other body cavity, they will primarily affect the cancer cells that are located in those areas. After surgery is performed to remove the tumor, anticancer drugs may be directly administered to the site of the brain tumor using a dissolving wafer. The stage of the cancer and the type will determine the type of chemotherapy used and how it is administered.
