Biological Therapy for Prostate Cancer

/Home/Prostate Cancer Treatment Options/Hormonal Therapy in Treating Prostate Cancer

Another kind of treatment is biological therapy. This treatment uses proteins to trigger the body's immune system to produce more white blood cells (or lymphocytes). Two lymphocytes that can attack and kill cancer cells are the T-cell and the B-cell. The proteins boost the ability of the T-cell and B-cell lymphocytes to kill cancer. Biological therapy can also be used in combination with surgery, radiation therapy or chemotherapy.

Hormone therapy is sometimes used to treat breast or prostate cancer. The hormone estrogen can make breast cancer tumors grow faster. Similarly, the hormone testosterone can make cancerous tumors in the prostate grow faster. Drugs that contain other hormones may be used to block the effects of estrogen and testosterone. In other cases, surgery to remove the ovaries or the testicles may be used. Removing these organs reduces the amount of estrogen or testosterone in the body.

Hormone therapy is often used in addition to chemotherapy or radiotherapy.

Other specialized treatments may be available. Your doctor may talk to you about these treatments if they are an option.
