Frequently Asked Questions

What does a positive BRCA1 or BRCA2 test result mean?

A positive test result indicates that the person has inherited a known alteration in the BRCA1 or BRCA2 gene. This means that the person has an increased risk for breast or ovarian cancer. However, the test only provides risk information and cannot predict if or when the person will develop cancer. It is also impossible to tell how a person will respond to medical treatment should cancer be diagnosed. It is important to note that many but not all woman who inherit an altered gene will develop breast or ovarian cancer.
