A genetic counselor is a health professional who specialises in family history and inherited risk: they help you record and make sense of the cancers in your family, explain what genetic testing can and cannot show, and support you in deciding whether testing is something you want. You usually reach one through a referral from your oncologist, surgeon, or primary care doctor, though the exact route varies. Whether testing is right for you is a personal decision to make with your own doctor — this article explains the role, not the decision.
Key Takeaways
- Genetic counselors specialise in the conversation around family history: gathering it carefully, explaining what patterns may mean, and talking through the possible benefits and limits of genetic testing.
- An appointment is mostly talking — your family’s cancers on both sides, recorded as fully as you can manage, with nothing to prepare beyond what you know and can find out.
- A referral usually comes from your oncologist, breast surgeon, or primary care doctor after a family-history conversation; some services accept other routes, and arrangements vary by area.
- A genetic counselor does not push testing. Their role includes helping you decide not to test, or to wait, if that is where you land.
- This article states no testing criteria and no risk figures: who may be offered testing, and what results mean, are individual and belong in your own appointments.
Who Genetic Counselors Are
Genetic counselors are trained health professionals whose specialism sits at the meeting point of genetics and conversation. They understand the science of inherited conditions, and they are equally trained in the human side: how people absorb uncertain information, how families communicate, and how a decision about testing ripples through relatives. Within cancer care, you will most often meet them through a hospital’s genetics or family-history service, connected to the breast team.
Our pillar guide to navigating breast cancer care maps the whole team around you, from navigators to financial counsellors. The genetic counselor is the member of that wider team whose territory is specifically your family’s story — not your treatment, which stays with your oncology team, but the pattern of cancers across your relatives and what, if anything, it suggests about inherited risk.
What a Genetic Counselor Actually Does
- Builds your family history properly. The heart of a first appointment is a careful family tree: which relatives had cancer, what kind, and at roughly what ages, on both your mother’s and your father’s side. Counselors are skilled at drawing this out — including the relatives people forget, such as paternal aunts, male relatives, and cancers in earlier generations.
- Explains the pattern, in plain language. They will talk through what your family’s pattern may suggest and — just as honestly — what it cannot tell you. Most breast cancers are not caused by a single inherited change, and a counselor will say plainly when a family pattern looks unremarkable as well as when it looks worth exploring.
- Explains testing honestly, both ways. What a test looks for, what a positive, negative, or uncertain result would and would not mean, and the practical and emotional implications — for you and for relatives who might share a result. This is a conversation about pros and cons, not a sales pitch.
- Supports the decision, whatever it is. Deciding to test, deciding to wait, and deciding not to test are all outcomes a counselor will support and record. The decision stays yours, made with your doctor.
- Helps with what follows. If testing goes ahead, the counselor is usually involved in explaining results and helping you think through what to tell relatives and how — one of the parts families find hardest.
Our article on Hereditary Breast and Ovarian Cancer Week describes the awareness observance built around exactly this territory — inherited patterns, previvors, and family conversations — and a genetic counseling appointment is, in a sense, the personal version of that week’s message.
How a Referral Usually Happens
The usual starting point is a family-history conversation with a doctor who already knows you: your oncologist or breast surgeon during treatment, or your primary care doctor. The conversation is short and ordinary: you describe the cancers in your family, the doctor considers the pattern with you, and if a genetics conversation seems appropriate, they make the referral. Some hospitals include a family-history discussion routinely in breast appointments, so the subject may be raised with you before you raise it yourself.
| Step | What usually happens |
|---|---|
| 1. Family-history conversation | You tell your doctor what you know of cancers in the family, on both sides; write it down beforehand so nothing is lost |
| 2. Referral | If a genetics appointment seems appropriate, your doctor refers you to the genetics or family-history service; waiting arrangements vary by area |
| 3. First appointment | Mostly conversation: the counselor builds your family tree in detail and explains what the pattern may and may not mean |
| 4. The testing decision | Testing is discussed — what it involves, what results could show — and you decide, with support, whether and when; nobody is rushed |
| 5. Results and follow-up | If you test, results are explained in a follow-up conversation, with time to plan what the result means for you and for relatives |
Routes vary: some services are hospital-based, some regional, and some appointments are offered by phone or video. If you believe a genetics conversation would help and it has not been offered, asking is entirely reasonable — the same plain asking approach described in our guide to asking for a patient navigator works here: “Given my family history, would a referral to a genetic counselor make sense for me?” Your doctor can explain the local route and whether they judge it appropriate in your case.
Preparing for a First Appointment
There is no examination and no test at a first appointment. The one preparation that genuinely helps is gathering family information beforehand, as far as you reasonably can:
- Both sides of the family. Inherited patterns pass through fathers as well as mothers, so paternal relatives count just as much — a point families often miss.
- Who, what, and roughly when. For each relative you know of: the relationship to you, the kind of cancer as best you know it, and the approximate age at diagnosis. Approximate is fine; perfect records are rare.
- Ask relatives while you can. Older relatives often hold the family’s medical memory. A gentle conversation now — the kind our awareness calendar encourages during family-history observances — can fill gaps no record office can.
- Bring your questions. Write down what you actually want to know: what a result would change, what it would mean for your children or siblings, what happens if you decide against testing.
- Do not worry about gaps. Small families, adoptions, estrangements, and lost histories are common, and counselors work with partial pictures every day. Bring what you have.
After the Conversation: Results and Relatives
If you decide to test, results take time, and the counselor will explain the local process and timescale at your appointment rather than this article guessing at them. When results come, they are explained in a conversation, not handed over cold: what was found, what it means in your situation, and what it does not mean — including the uncertain middle category that families rarely expect, where a change is found whose significance is not yet understood.
The other lasting work is family communication. A result can matter to siblings, children, and wider relatives, and the counselor can help you think about how to share information sensitively and accurately — who to tell, what to say, and what written summary the service can provide to pass on. Families differ; there is no script. What the counselor brings is experience of how this conversation has gone in many families before yours, which is quietly one of the most valuable parts of the service.
How They Differ From Other Guides on Your Team
Patients meet several professionals with overlapping-sounding roles. In brief: your patient navigator guides you through the process of care itself; an oncology social worker supports coping, family, and practical problems; and a genetic counselor’s territory is family history, inherited risk, and the testing conversation. They refer to one another constantly, and you do not need to choose the perfect door — any of them can point you to the genetics service if that is the conversation you need.
Individual services differ between hospitals and regions, so treat this article as a description of the role in general terms rather than a promise about any particular service. Your own care team can tell you exactly what exists where you are treated, and current general information about genetic counseling and inherited cancer risk is published by the National Cancer Institute at cancer.gov and the American Cancer Society at cancer.org.
Questions to Ask
- (Your doctor) Given my family history, would a referral to a genetic counselor make sense for me?
- (Your doctor) How do referrals to the genetics service work here, and what happens next?
- (The counselor) What does my family’s pattern suggest, and what can it not tell us?
- (The counselor) If I were tested, what could each kind of result mean — and what would it not change?
- (The counselor) What are the reasons people in my position sometimes decide not to test, or to wait?
- (The counselor) If a result mattered to my relatives, how would we handle telling them?
Frequently Asked Questions
Do I need a referral, or can I just book?
Usually a referral from your oncologist, surgeon, or primary care doctor is the route, because the genetics service works from your clinical picture as well as your family history. Routes vary by area and service, so if you want an appointment, start by asking one of your doctors — they can tell you how it works where you are.
Will the counselor tell me I should have genetic testing?
No. A genetic counselor’s job is to give you a clear picture — your family pattern, what testing could and could not show, and the implications either way — and then support your decision. Recommending for or against testing is not their role, and this article does not do it either. The decision belongs to you, made with your doctor.
What if I do not know my family history?
You are not alone, and it is not a barrier. Small families, adoption, estrangement, and relatives who never spoke about illness are all common. Bring whatever you do know — even fragments — and tell the counselor about the gaps. They are used to working with partial pictures, and the conversation can still be useful.
Is a genetic counseling appointment the same as a genetic test?
No. The appointment is a conversation: family history, explanation, questions. Testing is a separate step that only happens if you decide, with your doctor’s involvement, that you want it. Many people have the counseling conversation and then take time to think; some decide not to test at all, and that is a supported outcome.
Will my relatives be contacted or tested?
Not by the service acting on its own. Information flows through you: if a result could matter to relatives, the counselor helps you think about how to share it, and relatives then make their own decisions with their own doctors. Nobody is tested because a relative was.
