About Hormone Therapy

Some types of cancer depend on the hormones estrogen, progesterone, or testosterone to grow. Hormone therapy is designed to block or lower the amount of hormones in the body that promote growth of certain cancers. Sometimes these therapies attach to features on the surface of cancer cells called recepters. Sometimes the therapies work inside the cells. All steroid hormone therapies (Estrogen receptor and androgen receptor drugs) work inside the cell.
