Genetic testing is relatively new to cancer care. There are other gene mutations that can be tested for and will be discovered in the future. If you test “negative” for the BRCA mutation, you may still be at an increased risk for cancer if you have a strong family history of cancer or have other risk factors. Genetic testing is not % accurate. If a test is negative, a person still has a chance of developing breast cancer.

Abnormal BRCA1, BRCA2, and PALB2 genes may account for up to 10% of all breast cancers, or 1 .
When either of these genes is mutated, or altered, such that its protein product is not made or does not function correctly, DNA damage may not be repaired properly.
