Cancer risk associated with inherited BARD1 mutations
If you have tested positive for an BARD1 mutation, we recommend that you speak with a genetics expert who can look at your personal and family history of cancer and can help you choose the best plan for managing your cancer risk.
- Women with a BARD1 mutation have an increased risk of breast cancer, including triple-negative breast cancer. The estimated lifetime risk of breast cancer is as high as 40 percent.
- Currently, evidence is insufficient to conclusively show that a BARD1 mutation is associated with an increased risk of other cancers.
Research on the risk for cancer in people with BARD1 mutations is ongoing.
