Why it's doneBy Mayo Clinic staff
Your doctor may recommend external beam radiation for prostate cancer as an option at different times during your cancer treatment and for different reasons, including:
- As the only (primary) treatment for cancer, usually for early-stage cancer that is confined to your prostate
- In combination with other treatments, such as hormone therapy, for more serious cancer that's still confined to your prostate
- After surgery, to reduce the risk of cancer returning (adjuvant therapy)
- After surgery, when there is indication that your cancer has recurred either in the form of increased levels of prostate-specific antigen (PSA) in your blood or clinical evidence of cancer in your pelvis.
- To alleviate symptoms, such as bone pain, caused by advanced cancer that has spread beyond the prostate
