Most women worried about a family history turn out to have a risk far closer to average than they feared. The pattern matters more than the presence of a single case — and building a proper family history is something you can do before any appointment.
The first thing worth knowing is that the large majority of ovarian cancer is sporadic — it arises without any inherited predisposition, in women with no relevant family history at all. Only a minority is hereditary, most often through a BRCA1 or BRCA2 variant, and less commonly through Lynch syndrome or one of several other genes.
That matters because family history worry is rarely proportionate to family history risk. A woman whose grandmother's sister had ovarian cancer in her late seventies is carrying real anxiety and very little excess risk. A woman whose mother was diagnosed at 46 and whose maternal aunt had breast cancer at 41 is in a genuinely different position, and often less worried, because nobody has ever laid the pattern out for her.
So the useful question is not is there cancer in my family? — there is cancer in most families. It is: what is the pattern? How closely related, at what ages, how many, and on which side. Those four things do almost all of the work in a risk assessment, and you can gather them yourself before ever seeing anyone.
Most ovarian cancer arises with no inherited predisposition, in women with no relevant family history.
How close, what age, how many, which side. A single distant late-onset case adds very little.
The family history is the assessment. Gathering it before an appointment makes that appointment far more useful.
The single commonest reason hereditary risk is missed is that only the mother's side gets asked about. BRCA and Lynch syndrome variants pass through fathers exactly as readily as mothers — a father who carries a BRCA variant has a modest personal cancer risk and may never develop anything, so his side of the family looks unremarkable while he passes the variant to half his children. Families with few female relatives on the paternal side are particularly likely to miss it entirely. When a family history is taken properly, both sides are asked about, and male relatives count — breast, pancreatic, prostate and bowel cancer all belong in the record.

These are the distinctions that determine whether genetic testing is warranted. Find yours before worrying further.
Ovarian cancer in a mother, sister or daughter. Two or more relatives with ovarian or breast cancer on the same side of the family. Ovarian cancer diagnosed under 50. Breast and ovarian cancer in the same person. Breast cancer under 50 in a close relative, or in more than one relative. Male breast cancer at any age. Bowel or endometrial cancer under 50, which points to Lynch syndrome. A known BRCA or Lynch variant already identified in the family.
A single relative diagnosed in their seventies or eighties, particularly a distant one — cancer becomes more common with age and a late diagnosis is weak evidence of inheritance. Relatives on opposite sides of the family, since a hereditary variant travels down one line. Cancers not in the associated spectrum — lung, cervical and most others carry no ovarian implication. Relatives by marriage, who share no genes with you at all.
This is the single most useful preparation you can do, and it takes an evening rather than a project. Incomplete is fine — approximate is fine.
You, your siblings and children; your parents, aunts and uncles; your grandparents and their siblings. Three generations is what a genetics service works from, and gaps are expected rather than a problem — bring what you have.
Keep your mother's family and your father's family clearly distinct, because a hereditary variant travels down one line. Two cases on opposite sides mean far less than two on the same side, and conflating them is a common source of both false alarm and false reassurance.
Which cancer, how old they were at diagnosis, whether they are still living, and exactly how they are related to you. Age at diagnosis carries a great deal of weight — young onset is one of the strongest hereditary signals there is.
Not just ovarian and breast. Bowel, endometrial, pancreatic, prostate and stomach cancer all belong in the record, because they form part of the BRCA2 and Lynch syndrome patterns. Male relatives count fully — a male breast cancer is a strong signal.
Ashkenazi Jewish ancestry raises the prevalence of specific BRCA variants, as do certain other founder populations. And if any relative has already had genetic testing, that result is enormously valuable — ask for a copy of the actual report, not a summary.
Families lose records, relatives die young of other causes, and people misremember. Approximate ages and uncertain details are entirely usable. Bring the picture you can assemble rather than delaying because it is incomplete.
If a relative has had genetic testing, obtaining their actual laboratory report is the most valuable single thing you can do — it names the specific variant, which makes testing you quick, cheap and definitive.
Any single one of these is a reasonable reason to ask. You do not need several.
A mother, sister or daughter with ovarian cancer at any age is a recognised indication for genetic counselling.
Ovarian or breast cancer in two or more relatives on the same side of the family, which is the classic hereditary pattern.
Especially in a close relative, in more than one relative, or where one person had cancer in both breasts.
Uncommon and strongly associated with BRCA2. A single case in the family is enough to warrant referral.
Points towards Lynch syndrome, which raises ovarian risk alongside much higher bowel and endometrial risk.
If a relative carries an identified variant, testing you for that specific change is quick, inexpensive and definitive. See cascade testing.
Genetic counselling is not the same as genetic testing. Counselling establishes whether testing is warranted at all — and for many women the outcome is a well-founded reassurance rather than a test.
Who, which cancer, what age, which side. That information decides whether testing is warranted — and gathering it beforehand makes the appointment far more useful.

No referral needed and no cost for the first consultation. Most women who come with this worry leave reassured — and genetic counselling is in-house if it is warranted.
This is a genuinely common outcome and it is poorly explained almost everywhere. A woman with a strong family history is tested, nothing is found, and she is told the result is negative — which sounds like an all-clear and frequently is not.
A negative result means no variant was identified among the genes tested. Where the family pattern is striking, it may simply mean the responsible gene has not yet been discovered, or was not on the panel used. In that situation, management continues on the family history rather than on the test: enhanced breast surveillance may still be appropriate, and the ovarian conversation is still had, weighted by the pedigree rather than by a gene.
The most informative test in this situation is often not yours at all. If a living affected relative can be tested — the woman who actually had ovarian cancer, rather than you — a negative result in her is far more meaningful, because she is the person in whom a causative variant would be expected to show. If her test is negative, yours being negative means considerably more. This is worth raising, because it is frequently never offered.
It is not an all-clear when the family pattern is striking. The responsible gene may not have been on the panel, or may not yet be known.
Where the history is strong and no variant is found, surveillance and risk discussions continue based on the family pattern.
A negative result in the person who actually had the cancer is far more informative than a negative result in you.
If testing was done years ago on BRCA1 and BRCA2 alone, an updated multi-gene panel may now be worthwhile.
Most women who come in with this worry leave reassured, and that is a genuinely good outcome rather than a wasted appointment. Being told clearly why a great-aunt's diagnosis at 78 does not change your risk — with the reasoning laid out rather than a brisk dismissal — resolves something that searching never will.
Your first consultation at CION is free and runs to about 45 minutes, which is long enough to take a three-generation history from both sides properly. Bring what you have gathered, incomplete as it is. If a relative has had genetic testing, their actual laboratory report is the single most valuable document you can bring, because it names the specific variant.
Genetic counselling and BRCA and HRD testing are delivered in-house at CION, so if testing is warranted the counselling, the test and the plan afterwards happen with one team rather than across several referrals. Where cancer does develop, medical oncology — chemotherapy and maintenance therapy — is delivered in-house across 35+ centres. Risk-reducing and gynaecologic-oncology surgery is coordinated with specialist partner centres and may be billed there.
Free and unhurried. Long enough to take a three-generation history from both sides rather than a quick two questions.
Most women with this worry are at near-average risk. Being told why, with the reasoning, is a genuine outcome.
Where testing is warranted, counselling, testing and the plan afterwards happen with one team.

Higher than average, though usually far lower than most women in this position fear. Having a first-degree relative — a mother, sister or daughter — with ovarian cancer is a recognised indication for genetic counselling, and how much your own risk is raised depends heavily on the rest of the picture: her age at diagnosis, whether other relatives on that same side had ovarian or breast cancer, and whether any genetic testing was done. If your mother is living and has never been tested, testing her is often more informative than testing you, because she is the person in whom a causative variant would be expected to appear.
Usually very little, particularly if they were diagnosed at an older age. Cancer becomes more common with age, so a great-aunt diagnosed in her late seventies is weak evidence of anything inherited — most families have cases like this, and they reflect ordinary risk rather than a family pattern. What raises the significance is closeness of relationship, young age at diagnosis, several affected relatives on the same side, and whether the cancers involved fit a recognised hereditary spectrum. A single distant late-onset case rarely changes management at all.
Absolutely, and forgetting it is the single commonest reason hereditary risk is missed. BRCA and Lynch syndrome variants pass through fathers exactly as readily as mothers. A father carrying a BRCA variant has a modest personal cancer risk and may never develop anything, so his family can look entirely unremarkable while he passes the variant to half his children — and families with few female relatives on that side are particularly likely to miss it. Record both sides separately and include male relatives, since male breast, pancreatic, prostate and bowel cancer all form part of the pattern.
For each affected blood relative: which cancer, their age at diagnosis, whether they are still living, and exactly how they are related to you — kept clearly separate by side of the family. Go three generations if you can: your own generation, your parents' generation, and your grandparents' generation and their siblings. Include bowel, endometrial, pancreatic, prostate and stomach cancer alongside breast and ovarian. Note any Ashkenazi Jewish or other founder ancestry. Approximate ages and gaps are entirely fine — bring what you can assemble rather than delaying for completeness.
Not necessarily, and this is frequently explained badly. A negative result means no variant was found among the genes that were tested. Where your family pattern is striking, that may simply mean the responsible gene was not on the panel used, or has not yet been discovered. In that situation management continues based on the family history rather than the test — enhanced breast surveillance may still be appropriate and the ovarian conversation is still had. If testing was done some years ago on BRCA1 and BRCA2 alone, an updated multi-gene panel may now be worthwhile.
Where possible, yes, and it is frequently never offered. Testing a living relative who actually had ovarian or breast cancer is considerably more informative than testing you first, because she is the person in whom a causative variant would be expected to appear. If a variant is found in her, testing you for that specific change becomes quick, inexpensive and definitive. If her test is negative, your own negative result means far more than it otherwise would. Ask about this explicitly — it is one of the most useful questions you can put to a genetics service.
