Who Gets Hormone Therapy for Breast Cancer?
As part of the diagnosis process, tests are done to determine if the breast cancer cells have estrogen or progesterone receptors. If so, that means that growth of the cancer can be stimulated with these hormones. If a cancer is found to have these receptors, hormone therapy is recommended as part of the treatment plan.

Tamoxifen is a pill that has been used for over 30 years to treat breast cancer. It was first used in metastatic breast cancer (cancer that spread) because it slowed or stopped the growth of cancer cells in the body. Tamoxifen also decreases the chance that some early-stage breast cancers will recur in premenopausal or postmenopausal women and it can reduce the risk of cancer developing in the unaffected breast.
