Overview

Hormone therapy for prostate cancer is treatment to stop the male hormone testosterone from reaching prostate cancer cells in your body. Hormone therapy for prostate cancer is also known as androgen deprivation therapy.

Most prostate cancer cells rely on testosterone to help them grow. Hormone therapy cuts off the supply of testosterone or stops testosterone from reaching the cancer cells, causing cancer cells to die or to grow more slowly.

Hormone therapy for prostate cancer may involve medications or possibly surgery to remove the testicles.
