How does radiation therapy help in treating brain cancer?

ANSWER

Radiation therapy (also called radiotherapy) is the use of high-energy rays to kills tumor cells, thereby stopping them from growing and multiplying.

Radiation therapy may be used for people who cannot have surgery. In other cases, it is used after surgery to kill any tumor cells that may remain.

Radiation therapy is "local," which means that it affects only cells in its path. It typically does not harm cells elsewhere in the brain or body.
