Do You Need BRCA Genetic Testing After Genetic Counselling?

Counselling helps you decide whether to proceed; it is not a commitment to testing. Personal cancer history, the pattern of cancer in biological relatives, ancestry, previous genetic results, and the possible effect on treatment or risk management all shape the recommendation.

BRCA testing looks for inherited changes in genes involved in repairing damaged DNA. A harmful inherited change can influence some cancer-treatment choices and future risk-management discussions. Biological relatives may then choose to seek counselling about targeted testing.

A negative result does not erase cancer risk or explain every family pattern. Its meaning depends partly on whether a harmful family variant is already known. A test can also find a variant of uncertain significance, which means the laboratory cannot currently classify the change as harmful or harmless; this result is generally not used like a confirmed harmful variant.

Review the family history discussed in counselling and correct any missing diagnoses, ages at diagnosis, or biological relationships. Ask exactly which genes the laboratory will analyse, whether testing begins with a relative who has had cancer, and how each possible result would change your own medical plan.

Before giving consent, decide how and when you want results returned and whether you want a support person present. Consider how you may share a meaningful result with relatives while respecting privacy. Keep a copy of the laboratory report, because the precise variant wording matters for future care and family testing.

Recontact the genetics service if you learn of a new cancer diagnosis in a biological relative, find an existing family test report, become pregnant while considering risk-management options, or receive a genetic result through another clinic. These details can change which person or test is most informative.

A genetic result is not usually an emergency. However, contact your treating oncology team promptly if testing was requested to guide a current treatment decision and the result is delayed or unclear. Seek timely support if anxiety about testing is disrupting sleep, eating, work, or day-to-day functioning.

Ask: Why is BRCA testing being offered to me? Would a broader gene panel be relevant? What would a positive, negative, or uncertain result mean in my situation? Could the result affect treatment timing? Who can access it? How can relatives obtain appropriate counselling if a harmful variant is found?
