BRCA2 positive: what happens next?

A positive result is not a diagnosis of cancer. It can, however, affect breast, ovarian, prostate and pancreatic risk discussions, and it may provide useful information for adult blood relatives.

Look for the words pathogenic or likely pathogenic on the report and note whether the sample was blood, saliva or tumour tissue. A variant found only during tumour testing may have arisen in the cancer rather than being inherited, so a separate germline test may be offered.

BRCA2 supports repair of damaged DNA. An inherited harmful variant increases susceptibility to several cancers but cannot tell you whether cancer will develop, when it might appear, or which organ would be affected. An uncertain variant should not be interpreted as a confirmed positive result.

Schedule genetic counselling and bring the original report plus a family history from both parental branches. Discuss which breast imaging or clinical examinations apply, and whether ovarian risk-reducing surgery, prostate assessment, or pancreatic surveillance is relevant to your anatomy, age, medical history and family pattern.

If you already have cancer, tell the treating oncologist about the result because BRCA2 status can sometimes influence tumour testing and systemic treatment choices. When ready, give relatives the exact report rather than relying on memory; their clinicians can decide whether targeted testing is suitable.

Arrange an appointment for a new breast or chest lump, nipple change, persistent abdominal bloating, pelvic pain, early fullness, urinary difficulty, blood in urine, jaundice, or ongoing upper abdominal or back pain. Associated cancers can present with some of these features, but each symptom also has other possible explanations.

Use urgent care for severe pain, fainting, sudden breathing difficulty, heavy bleeding, or repeated vomiting with inability to drink. The need for prompt help depends on the symptom and how unwell you are, not on the genetic result alone.

Ask: Is my variant pathogenic and germline? Which organs should my plan cover? What are the benefits and drawbacks of each screening or preventive option? Could this result change current cancer treatment? How can relatives access testing for the same variant?
