Medicines to Reduce Breast Cancer Risk

+ -Text Size


What drugs are used to reduce the risk of breast cancer?

When drugs are used to reduce the risk of cancer in healthy people, it’s called chemoprevention. This is an important area of cancer research.

The drugs tamoxifen and raloxifene reduce the risk of breast cancer in women known to have an increased risk, and these drugs are approved for this use. Drugs called aromatase inhibitors can also lower breast cancer risk, but they are still being studied and are not approved for this use. Other compounds including dietary supplements are also being studied to find out if they might help reduce risk but to date, none have been shown to be helpful.
