Whole-brain radiation therapy (WBRT) involves treating the entire brain with small doses of radiation over a period of several days. It effectively kills microscopic and undetectable cancer cells not only around the tumor but also in other parts of the brain where they have not yet been detected with MRI scans.

WBRT can be used as a supplement to stereotactic radiosurgery, and it can be used in cases where multiple metastatic tumors are present. Potential adverse affects of WBRT include long-term radiation toxicity that can result in delayed, cognitive effects, including memory loss and personality changes, in up to 10 percent of patients.
