is a gene that helps repair damage to your . People who are born with changes—called mutations—in their gene have an increased risk for cancer.   

What are the cancer risks for people with a mutation?

Mutations in the gene have been linked to increased risk for breast cancer in women. Currently, it is not believed that mutations increase the risk for other cancers, but research on this is continuing.

Each of these topics is outlined in more detail in the sections highlighted below.
