Radiation Therapy for Pituitary Tumors

Doctors administer radiation therapy for pituitary tumors that:

  • Cannot be completely removed safely
  • Grow quickly
  • Do not shrink with medication
  • Are located in areas of the brain where surgery is unsafe
  • Recur after surgery

Radiation therapy for pituitary tumors does not usually work quickly. It can take several months or years to control a pituitary tumor’s growth or stop hormone production.

Types of radiation therapy for pituitary tumors:
