Q: How is radiation used for the treatment of brain tumors?

Radiation damages cancer cells and inhibits their ability to reproduce. For some patients, whole-brain radiation may be used to treat multiple tumors at once. This treatment may be followed by radiosurgery to target specific tumors, if appropriate. Radiation therapy or radiosurgery may also be used following conventional surgery to remove a tumor in order to destroy any remaining cancer cells outside the primary tumor site. In some cases, radiosurgery or radiotherapy may be used alone as the first line of treatment. You and your treatment team will discuss your options and what type of radiation might be appropriate for your particular case.
