What does a BRCA gene mutation mean in women?

A confirmed result can guide earlier or more intensive surveillance, discussions about risk-reducing options, and testing for adult biological relatives. Decisions are personalised rather than automatic.

BRCA1 and BRCA2 normally contribute to DNA repair. A harmful inherited variant can reduce this protective function and is associated with susceptibility to breast and ovarian cancer as well as some other cancers. The precise implications vary by gene, variant, age, health history and family history.

The laboratory wording matters. A pathogenic or likely pathogenic result has a different clinical meaning from a variant of uncertain significance. Genetics professionals can also explain that the variant may have been inherited from the mother's or father's side of the family.

Meet with a genetic counsellor and a clinician familiar with hereditary cancer. Take the full report and, if possible, information about cancers on both sides of the family. Your team can map out breast surveillance and discuss ovarian risk management alongside fertility goals, menopause effects and other health priorities.

Risk-reducing medicines or surgery may be options for some women, but each has benefits, limitations and possible effects that deserve an unhurried discussion. Adult relatives can decide whether to have targeted testing once the exact family variant has been confirmed.

Arrange prompt assessment for a new breast or underarm lump, nipple discharge, skin dimpling, nipple inversion, or a persistent change in breast shape. A BRCA result cannot determine the cause of a symptom, so examination and appropriate imaging are needed.

Persistent abdominal swelling, pelvic or abdominal pain, feeling full unusually quickly, or a sustained change in bladder or bowel habits should also be discussed with a clinician. Seek emergency care for severe sudden pain, collapse, breathing difficulty or uncontrolled bleeding.

Ask how the exact variant affects your surveillance, what each risk-reducing choice can and cannot achieve, and how treatment could influence fertility, breastfeeding, bone health or menopause. Confirm which clinician coordinates follow-up and how relatives can access appropriate counselling.
