Hormone therapy is the use of hormones in medical treatment. Treatment with hormone antagonists may also referred to as hormonal therapy or antihormone therapy. The most general classes of hormone therapy are oncologic hormone therapy and hormone replacement therapy, of which there are various kinds (e.g., for menopause, for male menopause, or for gender change).
Hormone therapy is another form of systemic therapy. It is most often used as an adjuvant therapy to help reduce the risk of the cancer coming back after surgery. Hormone therapy for cancer is the use of medicines to block the effects of hormones. It uses one or more female hormones, commonly estrogen and progestin and sometimes testosterone, to treat symptoms of menopause. Hormonal therapy can slow down or prevent cancer cells from growing.
