What is the BRCA test?

The BRCA gene test is a blood test that uses DNA analysis to identify harmful changes (mutations) in either one of the two breast cancer susceptibility genes — BRCA1 and BRCA2.

People who inherit mutations in these genes are at an increased risk of developing breast cancer and ovarian cancer compared with the general population.

The BRCA gene test is offered to those who are likely to have an inherited mutation based on a personal or family history of breast cancer or ovarian cancer. The BRCA gene test isn't routinely performed on people at average risk of breast and ovarian cancers.

The results of genetic testing aren't always clear. A positive result means you carry a gene mutation that increases your risk of cancer and you can work with your doctor to manage that risk. A negative result may mean that you don't have the mutation or that you might have a gene mutation doctors haven't discovered yet. Your test might also identify a gene variant that doctors aren't certain about. In these situations, it's not always clear what the results mean for your cancer risk.

Most people considering genetic testing undergo genetic counseling. Genetic counseling can help you understand what the results could mean for your health, help you decide whether genetic testing is right for you, and recommend a specific set of genetic tests based on your family history.

You can acquire this testing through your primary care physician or your OBGYN. If you would like to know where to get BRCA testing, please call our office at 512-776-1000 today and we can help guide you!
