tamoxifen

tamoxifen , synthetic hormone used in the treatment of breast cancer . Introduced in 1978, tamoxifen is used to prevent recurrences of cancer in women who have already undergone surgery to remove their tumors. In 1998, a large study of healthy women at high risk for breast cancer showed that tamoxifen can also prevent first occurrence of the disease: women who took the drug had a 45% lower incidence of cancer that those who received a placebo. However, adverse effects (including uterine cancer) and other concerns await further study.
