Tamoxifen is a medication used to treat some types of breast cancer in men and women, as well as to lower a woman's chance of developing breast cancer if she has a high risk.
It blocks the activity of estrogen (a female hormone) in the breast, which may stop the growth of some breast tumors that need estrogen to grow.
It is used to treat early breast cancer in women who have already been treated with surgery, radiation, and/or chemotherapy.
It is also used to reduce the risk of developing a more serious type of breast cancer in women who have had ductal carcinoma in situ.
Some people take tamoxifen to lower the risk of developing breast cancer.
It is important to take tamoxifen exactly as prescribed by a doctor, and to use a barrier form of birth control while using it and for at least 2 months after treatment ends.
