What to expect from BRCA genetic testing for ovarian cancer

BRCA1 and BRCA2 changes can be inherited and can affect cancer risk. For someone with ovarian cancer, a result may help the oncology team consider treatment choices, future risk discussions and whether relatives should seek counselling. Testing looks for a genetic change; it does not replace scans, pathology or examination, and it does not explain every cause of ovarian cancer.

The report may find a harmful change, find no harmful change in the genes tested, or identify a variant whose significance is unclear. If a harmful inherited change is found, relatives may be offered targeted testing. The result should be explained in the context of your diagnosis, family history and treatment plan.

Bring details of cancers in close relatives and any earlier genetic reports. Ask whether the test is inherited-risk testing, tumour testing, or both, because these answer different questions. Confirm how the sample will be collected and when the result will be discussed. Keep the appointment with your oncology team to review whether the result changes treatment, follow-up or family conversations. Do not stop treatment while waiting for testing.

Testing itself is not an emergency. Contact your oncology or genetics team if the result is difficult to understand, if family discussions feel overwhelming, or if you need help arranging counselling for a relative. Seek urgent medical advice for severe abdominal pain, persistent vomiting, difficulty breathing, heavy bleeding or sudden deterioration, regardless of your genetic result.

Ask what kind of BRCA test is planned, how the result could affect current treatment, whether a tumour result suggests inherited testing, how relatives can be informed, and what follow-up is recommended for each possible result.
