Tamoxifen, or commonly for its brand name as Nolvadex, works by binding into the breast tissues before estrogen can bind on the tissue receptors. As what we might know, Breast cancer is fed through estrogen. However, tamoxifen does not suppress estrogen production, which is one of its advantages. Therefore, other parts of the body can still benefit with estrogen
