Why it's done

Hormone therapy for prostate cancer is used to stop your body from producing the male hormone testosterone, which fuels the growth of prostate cancer cells.

Your doctor may recommend hormone therapy for prostate cancer as an option at different times and for different reasons during your cancer treatment.

Hormone therapy can be used:

  • In advanced (metastatic) prostate cancer, to shrink the cancer and slow the growth of tumors — which might relieve signs and symptoms
  • In prostate cancer that recurs after treatment
  • In locally advanced prostate cancer, to make external beam radiation therapy more effective
  • In those with a high risk of recurrence after initial treatment, to reduce that risk
