Whole brain radiotherapy
see also Prophylactic cranial irradiation.
A type of external radiation therapy used to treat patients who have cancer in the brain. It is often used to treat patients whose cancer has spread to the brain, or who have more than one tumor or tumors that cannot be removed by surgery. Radiation is given to the whole brain over a period of many weeks. Also called WBRT and whole-brain radiation therapy.
Sometimes the whole brain is treated with radiation when cancer is in many areas. This may also be done to keep cancer from spreading to the brain.
