FRABOC was short for Familial Risk Assessment – Breast and Ovarian Cancer. It was a clinical assessment tool created by Cancer Australia to help general practitioners and practice nurses evaluate a woman’s potential breast and ovarian cancer risk by looking closely at her family history.

FRABOC was not designed as a typical online calculator that patients could complete independently. Instead, a healthcare professional would use it during a consultation. Information about relatives, previous cancer diagnoses, ages at diagnosis, and the types of cancer occurring within the family would be entered into the assessment. The resulting risk category could then help guide discussions about screening, referrals, and possible follow-up.
Today, FRABOC is no longer in operation. Cancer Australia retired the tool, and it was subsequently replaced by iPrevent, a more detailed risk assessment system. However, the basic questions behind FRABOC remain important because family history continues to play a major role in evaluating inherited breast and ovarian cancer risk.
For anyone who has encountered the term FRABOC in an old medical letter, referral document, or Australian healthcare resource, its disappearance can be confusing. Understanding what the tool did, why it was retired, and what replaced it makes the terminology much easier to put into context.
What Was FRABOC Designed to Do?
FRABOC was essentially created to make family-history assessment more structured.
Before clinical tools such as FRABOC, a GP might hear that a patient’s mother or sister had breast cancer and then make a judgment based on their clinical experience and general guidelines. The challenge was that family cancer patterns can be complicated, and an isolated diagnosis does not necessarily indicate an inherited cancer syndrome.
FRABOC provided a more consistent way of approaching the assessment.
A clinician could record information such as:
- Which relatives had experienced cancer
- Whether the relatives were on the mother’s or father’s side
- The age at which cancer was diagnosed
- Whether the cancer was breast or ovarian cancer
- Whether several relatives had developed related cancers
- Whether a known genetic mutation was present in the family
The information was then used to place the patient into a broader risk category.
This gave healthcare professionals a clearer starting point for deciding whether ordinary population screening was appropriate or whether additional assessment might be warranted.
Who Was FRABOC Intended For?
FRABOC was primarily a clinical tool, rather than a consumer health calculator.
It was intended for use by professionals such as GPs and practice nurses during patient consultations. A woman would therefore generally encounter FRABOC indirectly: the clinician would collect her family-history information, complete the assessment, and then discuss the result with her.
That distinction is important because some online references make FRABOC sound like a self-service risk calculator. It was not designed in that way.
The purpose was to support a healthcare professional’s judgment, not to replace a medical consultation.
Why Is FRABOC No Longer Available?
FRABOC was eventually discontinued by Cancer Australia. As a result, people searching for an official, current version may only find older documents, historical references, or healthcare resources that still mention the name.
This can create confusion, particularly when someone finds FRABOC mentioned in an older referral letter or medical document.
The retirement of FRABOC does not mean that family-history assessment stopped being important. Rather, approaches to estimating breast cancer risk became more sophisticated. Modern assessment methods can incorporate a wider range of information instead of relying primarily on family history.
This helped pave the way for newer tools capable of producing a more individualised estimate of risk.
What Replaced FRABOC? Understanding iPrevent
The modern Australian tool associated with breast cancer risk assessment is iPrevent.
Developed through the Peter MacCallum Cancer Centre, iPrevent was designed to provide a more comprehensive assessment than the older FRABOC approach. It can consider family history alongside a range of other factors that may influence breast cancer risk.
Depending on the assessment, these factors can include:
- Family history of breast and related cancers
- Breast density
- Reproductive history
- Hormonal factors
- Previous breast biopsies
- Body weight
- Lifestyle-related factors
- Other relevant personal information
Another major difference is the way the result is presented.
Rather than simply placing someone into one of three broad FRABOC categories, iPrevent can provide an estimated five-year and lifetime breast cancer risk. This gives clinicians and patients a more individualised picture of risk.
The tool can also help inform discussions about possible management strategies, including screening approaches and, where appropriate, risk-reduction options.
iPrevent incorporates established statistical models, including IBIS and BOADICEA, and can use the model considered most appropriate for the patient’s particular risk profile.
FRABOC vs. iPrevent
| Feature | FRABOC | iPrevent |
|---|---|---|
| Current status | Retired | Current assessment tool |
| Primary approach | Mainly family-history based | Multiple personal and family risk factors |
| Typical users | GPs and practice nurses | Patients and healthcare professionals |
| Risk result | Broad risk category | Estimated five-year and lifetime risk |
| Family history | Yes | Yes |
| Other risk factors | Limited | Includes several additional factors |
| Statistical models | Earlier clinical framework | Includes validated models such as IBIS and BOADICEA |
| Management guidance | Supported clinical decision-making | Provides more detailed risk-management information |
If you are researching your current breast cancer risk, looking for FRABOC is therefore unlikely to be useful. A contemporary assessment such as iPrevent, together with advice from your GP, is a more relevant starting point.
The Three Risk Categories Associated With FRABOC
One of the most useful things to understand about FRABOC is the three-level risk framework it used.
Although the original tool has been retired, the general concept of dividing women into broad levels of risk remains useful when discussing family history.
The categories can broadly be understood as follows:
| Risk category | General description | Possible implications |
|---|---|---|
| Average or slightly above average risk | The majority of women, without a strong inherited pattern | Routine population screening is generally appropriate |
| Moderately increased risk | A more noticeable family-history pattern without clear evidence of a major inherited syndrome | Additional or earlier screening may sometimes be considered |
| Potentially high risk | Strong family patterns or evidence suggesting an inherited predisposition, such as a known BRCA mutation | Specialist assessment, genetic counselling, and individualised management may be appropriate |
These categories were never intended to predict exactly who would or would not develop cancer.
Instead, they provided a practical way for clinicians to decide whether a patient’s situation looked similar to the general population or whether further investigation might be worthwhile.
Average or Slightly Above Average Risk
Most women assessed through family-history-based screening fall into the lower-risk category.
Having a relative who has experienced breast cancer does not automatically mean that a woman has a hereditary cancer syndrome. Breast cancer is relatively common, so diagnoses can occur within families without being caused by a specific inherited mutation.
For women in this category, standard population screening is generally the appropriate approach unless other factors indicate otherwise.
Moderately Increased Risk
The middle category describes women whose family history is more significant than that of the general population but does not necessarily indicate a clearly inherited cancer syndrome.
For example, several relatives may have had breast cancer, or a relative may have been diagnosed at a comparatively young age.
Depending on the overall circumstances, a healthcare professional may recommend additional assessment or changes to the usual screening approach.
The important point is that moderate risk does not mean that cancer is inevitable. It means that the person’s estimated risk may be sufficiently different from average to justify closer attention.
Potentially High Risk
The highest category was intended for women whose family history suggested a stronger possibility of inherited cancer susceptibility.
Examples can include families with multiple breast or ovarian cancer diagnoses, particularly when cancers occurred at younger ages, or families in which a pathogenic BRCA1 or BRCA2 variant is already known.
Women with these types of patterns may be referred to a specialist service, such as a Family Cancer Clinic, where genetic counselling and more detailed risk assessment can be considered.
What Does Family History Really Tell You?
Family history can provide valuable clues, but it should not be interpreted too simply.
Having one relative with breast cancer does not automatically mean that you are at high risk. Breast cancer is common enough that many families will have at least one affected relative even when there is no inherited cancer syndrome.
What matters more is the pattern of cancer within the family.
Clinicians may pay particular attention when they see combinations such as:
- Several relatives with breast cancer
- Multiple relatives with ovarian cancer
- Breast and ovarian cancer occurring within the same family
- Cancer diagnosed at a relatively young age
- Breast cancer in a male relative
- Several affected relatives on the same side of the family
- A known BRCA1 or BRCA2 mutation
- Other features that suggest a hereditary cancer syndrome
No single factor should be interpreted in isolation. The overall family history is what helps determine whether further assessment is appropriate.
Your Father’s Family History Matters Too
One common misunderstanding is that breast cancer risk is primarily something inherited through the mother’s side of the family.
That is incorrect.
Genetic variants associated with hereditary breast and ovarian cancer can be inherited from either parent. A father can carry a relevant genetic variant and pass it to his daughter even if he never developed breast cancer himself.
For that reason, a proper family history should include both sides of the family.
When preparing for an appointment, think beyond your mother, sisters, and maternal grandmother. Consider your father’s parents, sisters, brothers, and other close relatives as well.
Preparing for a Family Cancer Risk Appointment
If you are concerned about your family’s history of breast or ovarian cancer, preparing some information before seeing your GP can make the consultation much easier.
Try to find out:
- Which relatives were diagnosed
- What type of cancer they had
- How old they were when diagnosed
- Whether the cancers occurred on your mother’s or father’s side
- Whether anyone has undergone genetic testing
- Whether a BRCA1 or BRCA2 mutation has been identified
- Whether several relatives have had related cancers
You do not need a perfectly documented family tree before making an appointment.
Even approximate information can be helpful, and your doctor can explain what additional details would be useful.
If someone in the family has already undergone genetic testing, having access to the actual test result or medical report can be particularly useful. A confirmed genetic result can provide much more information than trying to estimate risk from memory alone.
What a GP May Ask You
A family-history consultation can involve surprisingly straightforward questions.
Your GP may want to know which relatives had cancer, their relationship to you, their age when diagnosed, and whether the cancers occurred on your mother’s or father’s side.
They may also ask whether ovarian cancer has appeared in the family or whether anyone has previously been assessed for an inherited cancer syndrome.
The goal is not simply to count how many people had cancer.
The timing, type of cancer, relationship between affected relatives, and genetic information can all influence how the family history is interpreted.
Other Breast Cancer Risk Models to Know About
Family-history assessment does not always end with one risk calculator.
Specialist cancer services may use additional models when a person’s family history is complicated or when a more detailed genetic assessment is required.
One example is CanRisk, which provides an online interface associated with the BOADICEA model. It can be useful when specialists need to examine a more complex combination of family history and genetic risk factors.
Different risk models have different strengths and limitations. This is one reason a specialist may perform another assessment after a patient has already discussed their history with a GP.
A second assessment does not necessarily mean that the original assessment was incorrect.
It may simply mean that a specialist has access to more detailed information and is using a model designed for a more complex risk calculation.
Why Risk Assessment Can Be Helpful
Knowing that cancer has occurred in your family can create a difficult type of uncertainty.
You may know that your mother, sister, aunt, or another relative had cancer, but still have no idea what that means for you personally.
That uncertainty can sometimes be more stressful than having a concrete assessment.
A risk assessment cannot guarantee what will happen in the future. It cannot completely remove the possibility of cancer either.
What it can do is turn a vague concern into something that can be discussed and managed.
Depending on the result, you may simply be reassured that standard screening remains appropriate. Alternatively, you may be advised to have additional screening, see a specialist, or consider genetic counselling.
The value lies in having a clearer plan rather than trying to interpret your family history alone.
FAQs About FRABOC
Is FRABOC still available in Australia?
No. FRABOC has been retired and is no longer used as the current Australian family-history risk assessment tool.
Modern resources, including iPrevent, have taken its place.
What does FRABOC stand for?
FRABOC stands for Familial Risk Assessment – Breast and Ovarian Cancer.
It was a clinical assessment approach used to help healthcare professionals estimate breast and ovarian cancer risk from a patient’s family history.
What replaced FRABOC?
FRABOC was replaced by newer approaches, most notably iPrevent for breast cancer risk assessment.
Unlike the older three-category framework, iPrevent can provide a more individualised estimate of five-year and lifetime breast cancer risk.
Can I use iPrevent without a doctor?
iPrevent can be completed online, but the results are best discussed with a healthcare professional.
A GP can help interpret the result in the context of your medical and family history and determine whether any further screening, referral, or genetic assessment is appropriate.
Does having one relative with breast cancer mean I am high risk?
Not necessarily.
A single relative with breast cancer does not automatically place someone in a high-risk category. Clinicians generally look at the wider pattern, including the number of affected relatives, their ages at diagnosis, the types of cancer involved, which side of the family they are on, and whether a relevant genetic mutation has been identified.
Where to Go From Here
FRABOC may no longer be available, but the problem it was designed to address has not disappeared.
Family history remains an important part of understanding breast and ovarian cancer risk. The main difference is that modern tools can consider a broader range of information and provide a more personalised estimate.
If you have found FRABOC mentioned in an old medical document, there is no need to search endlessly for the retired tool. Instead, speak with your GP about your current risk and ask whether an assessment such as iPrevent would be appropriate.
Before your appointment, gather whatever information you can about cancer diagnoses on both sides of your family, including the ages of affected relatives and any available genetic-testing results.
Most importantly, remember that having cancer somewhere in your family does not automatically mean that you will develop it yourself. A proper risk assessment can provide a much clearer picture and, when necessary, help you and your healthcare team decide what should happen next.
