Breast cancer prevention: Medicines that reduce risk

How it works

Like tamoxifen, raloxifene (Evista) is a kind of medicine known as a selective estrogen receptor modulator (SERM). It is typically taken by mouth once a day for five years.

Raloxifene works by blocking estrogen's effects in the breast and other tissues. However, unlike tamoxifen, raloxifene doesn't have estrogen-like effects on the uterus and does not increase the risk of uterine cancer.
