​Hormone therapy

About hormone therapy

Hormone therapy is a form of systemic therapy—administering drugs that travel throughout the body, rather than being delivered directly to the cancer—that works to add, block or remove hormones from the body to slow or stop the growth of cancer cells. At Cancer Treatment Centers of America® (CTCA), we use hormone therapy to fight various types of cancer.

Hormones are known as the body’s chemical messengers and are produced in the endocrine glands, which include glands such as the thyroid, pancreas, ovaries in women and testicles in men. Some hormones encourage the growth of some cancers, such as breast and prostate. But, in some cases, they may kill, slow or stop cancer cells from growing.

Hormone therapy usually involves taking medications that prevent cancer cells from getting the hormones they need to grow. In some cases, your doctor may surgically remove the gland responsible for hormone production. Our physicians may use hormone therapy in combination with other cancer treatments, such as chemotherapy and radiation therapy.
