My mother told me about my aunt almost as an afterthought.
We were having tea. She said her sister had been diagnosed with breast cancer. Caught early. She was going to be fine.
And she was. But something shifted in me that afternoon that I couldn’t shake for a long time. Not panic. More like a quiet awareness I hadn’t carried before. Cancer had happened in my family. And I didn’t know what that meant for me.
I think a lot of women know that feeling.
What FRABOC Was
For a long time in Australia, the tool that helped answer that question — at least in a structured, evidence-based way — was something called the Familial Risk Assessment – Breast and Ovarian Cancer, known as FRABOC.
It was an online risk assessment tool developed through Cancer Australia, designed to be used by GPs and nurses in conversation with their patients. It wasn’t something you’d stumble across yourself and fill in alone on a Sunday night. It was a clinical tool — a way for health professionals to take a family history and translate it into a meaningful risk category, so that the conversation could go somewhere useful rather than ending in vague reassurance or unspoken worry.
FRABOC is no longer available. Cancer Australia has moved to a newer, more comprehensive tool called iPrevent, developed by the Peter MacCallum Cancer Centre, which incorporates a broader range of personal and family risk factors. But the questions that FRA-BOC asked — the careful accounting of who in your family was diagnosed, and when, and with what — those questions still matter. They matter perhaps more than ever, because the research has only gotten clearer about what family history does and doesn’t tell us about risk.
What Family History Does and Doesn’t Mean
Having a relative who had breast cancer does not automatically mean your risk is significantly higher. That is the first thing worth understanding.
Breast cancer is common. In Australia roughly one in seven women will develop it in their lifetime. In many families a diagnosis will occur simply because the disease is prevalent. One older relative with breast cancer may not change your individual risk much at all.
What changes the picture is pattern.
The signals that FRABOC weighted most heavily were things like multiple relatives on the same side of the family being diagnosed. A relative diagnosed under fifty. A family history of both breast and ovarian cancer together. A male relative with breast cancer. A known BRCA1 or BRCA2 gene mutation already identified in the family.
One thing many women don’t realise is that your father’s side matters just as much as your mother’s. A BRCA gene mutation can come from either parent. A father who carries it but has never been diagnosed can still pass it to a daughter. So a thorough family history looks at both sides.
The Three Categories
FRABOC classified women into three broad risk categories, and it is worth understanding what they mean — both clinically and emotionally.
- The vast majority of women — more than 95% — fall into the category described as at or slightly above average risk. This includes women with no family history at all, and also women with one or two relatives who have had breast cancer in circumstances that don’t suggest a strong inherited pattern. Being in this category doesn’t mean cancer is impossible. It means your risk is close to the population average — which in Australia is already something we screen for, but not something that requires additional specialist intervention.
- A smaller number of women fall into moderately increased risk — where the family history is more notable but still doesn’t clearly indicate a high-risk inherited syndrome. Women in this category may be recommended more frequent screening or earlier starting ages for mammograms.
- Then there is the category of potentially high risk — where the family pattern is significant enough to warrant referral to a Family Cancer Clinic. These clinics can offer more detailed assessment, genetic testing if appropriate, and genuinely individualised management plans. For women who land here, a referral is not a sentence. It is access to people who specialise in exactly this kind of complexity, and who can give a much clearer picture than any online tool alone.
The important thing to understand is that most women who go through this process discover they are in the first category. The assessment exists not to confirm fears but to give them appropriate shape — to say, with some precision, here is where you actually sit, rather than leaving the question open-ended and therefore infinitely expandable in the imagination.
The Part Nobody Talks About
I want to say something about the experience of carrying uncertainty on this topic, because I think it gets overlooked in conversations that are focused purely on clinical information.
There is a particular kind of anxiety that comes with having a family history of something you can’t control. It is not the acute anxiety of a diagnosis or a crisis. It is quieter and more persistent — a low-level awareness that sits in the background of ordinary days. You notice things differently. You are perhaps more attuned to your own body than you’d otherwise be, which can be helpful, but can also become its own source of distress when every unfamiliar sensation becomes something to interpret.
I have known women who avoided getting any kind of risk assessment done specifically because they were afraid of what they might find out. The logic, if you examine it closely, is understandable: if you don’t know something, you can’t be affected by it. But that is not really how anxiety works. The not-knowing doesn’t protect you from the worry. It just means the worry has no ground to stand on, no facts to work with, no boundary — and boundaryless anxiety tends to fill all available space.
What I’ve observed — in myself and in people I’ve known — is that getting actual information, even information that confirms elevated risk, tends to reduce that ambient anxiety rather than increase it. Not immediately, and not without its own emotional processing. But having a real picture, however complicated, is almost always more manageable than a formless dread.
There is something in the act of asking the question properly that changes your relationship to it. FRA-BOC was, in a way, a mechanism for asking the question properly. It gave the conversation structure. It meant that the answer — whatever it was — could be clear.
What Changed After FRABOC
The shift to iPrevent reflects how much this field has developed. The newer tool considers breast density, reproductive history, hormone use and other personal factors alongside family history. It gives a five-year and lifetime risk estimate rather than a broad category.
That is better medicine. Risk is not one variable.
But what FRA-BOC stood for has not changed. Family history is information. It deserves to be taken seriously and interpreted properly. Women deserve to know where they stand rather than carrying the question in silence.

Going Back to My GP
After that afternoon at my mother’s table I made an appointment. Not urgently. My aunt was recovering well and I was not in a crisis. But I realised I had never properly accounted for my family history in a clinical sense.
My GP asked careful questions. Both sides. Ages at diagnosis. Types of cancer. She worked through a risk framework and placed me in the average risk category. She explained what that meant for screening. I left without any dramatic revelation. But I left knowing something I hadn’t known before.
That is what FRABOC was always trying to make possible. Not a diagnosis. Not a scare. Just a proper answer to the question that a lot of women carry quietly.
If you have that question sitting somewhere, take it to your GP. The answer is almost certainly less frightening than the wondering.
