Hormone Therapy
Hormone therapy stops cancer cells from growing by blocking the action of hormones. Hormones are substances produced by glands in the body and circulated in the bloodstream. The presence of some hormones can cause certain cancers to grow. If tests show that the cancer cells have receptors where hormones can attach, drugs can be used to reduce the production of hormones or block them from working. In hormone therapy, progesterone-like drugs known as progestins are used to slow the growth of cancer cells, usually in a pill form or by injections.
