Tamoxifen, also known by the brand name Nolvadex, is one of the more commonly prescribed medications to prevent breast cancer recurrence, and when used appropriately, may reduce the risk of recurrence (of breast cancer coming back) by roughly 50 percent. The drug may also be used to reduce the chance that a woman will develop breast cancer in the first place, or to slow the growth of metastatic breast cancer.

It is classified as a selective estrogen receptor modulator (SERM) along with the medication Evista (raloxifene). Tamoxifen is usually not considered beneficial for those who have estrogen or progesterone negative breast cancer. But they do know that some breast cancer cells are sensitive to estrogen. In order to fuel that growth, estrogen must attach itself to those breast cancer cells. Doctors think that tamoxifen stops estrogen from attaching to the cell. No estrogen means no growth for these types of breast cancer cells. Tamoxifen also keeps healthy breast cells from growing and multiplying. That way, it also reduces the number of cells that could become cancer. In a study of more than 13,000 women at high risk for breast cancer, scientists found that women who took tamoxifen for 5 years had fewer breast cancers than women who took a placebo. Newer research suggests that taking the drug for 10 years lowers the risk even more.

ER-positive and PR-positive breast cancer cells have receptors (proteins) that attach to estrogen, which helps them grow. There are different ways to stop estrogen from attaching to these receptors. Hormone therapy is a form of systemic therapy, meaning it reaches cancer cells almost anywhere in the body and not just in the breast. It's recommended for women with hormone receptor-positive (ER-positive and/or PR-positive) breast cancers, and it does not help women whose tumors are hormone receptor-negative (both ER- and PR-negative). Hormone therapy is often used after surgery (as adjuvant therapy) to help reduce the risk of the cancer coming back. Sometimes it is started before surgery (as neoadjuvant therapy) as well. Hormone therapy can also be used to treat cancer that has come back after treatment or that has spread to other parts of the body.
