BRCA Genetic Testing for Breast Cancer Risk
BRCA1 and BRCA2 are genes involved in DNA repair. Certain inherited (germline) changes can increase the risk of breast, ovarian, and other cancers. Testing is typically most helpful when guided by personal and family history and paired with genetic counseling.
When genetic testing is most useful
Major guidelines recommend risk assessment first. People with a personal or family history suggesting higher likelihood of harmful BRCA changes may benefit from genetic counseling and, if appropriate after counseling, genetic testing. Sources: USPSTF, NCI (NIH), CDC
- Testing is recommended for those at increased risk based on history or ancestry (not as a blanket screen). Source: USPSTF
- Genetic counseling helps interpret results and discuss next steps for prevention or early detection. Source: CDC
- A BRCA test can’t predict with certainty whether someone will develop cancer—results guide risk management. Source: MedlinePlus (NIH)
What is BRCA genetic testing?
BRCA genetic testing looks for specific DNA changes (variants) in the BRCA1 and BRCA2 genes that can increase the likelihood of developing certain cancers. Testing is typically performed using a blood or saliva sample. Sources: NCI (NIH), Mayo Clinic
Who should consider it?
- People with a personal or family history of breast cancer (especially at younger ages)
- History of ovarian cancer, male breast cancer, pancreatic cancer, or high-risk/metastatic prostate cancer in the family
- Known BRCA mutation in a close relative
- Certain ancestries associated with higher likelihood of BRCA mutations (discuss with a clinician)
Understanding possible results
Positive (pathogenic / likely pathogenic)
A harmful BRCA change was found. This can raise cancer risk, but it does not mean cancer is certain. Your plan may include enhanced screening, risk-reduction strategies, and family risk discussions.
Negative or Variant of Uncertain Significance (VUS)
A negative result doesn’t always eliminate hereditary risk—especially if no known family mutation exists. A VUS means the finding isn’t currently understood well enough to change care on its own; management is based on personal/family history.
