Fraboc, short for Familial Risk Assessment – Breast and Ovarian Cancer, was an Australian clinical tool designed to help health professionals assess a woman’s risk of breast and ovarian cancer using her family history. Although Fraboc is no longer available, understanding how it worked is still useful because family history remains an important part of modern cancer-risk assessment.
Today, Australian clinicians can use newer tools such as iPrevent, which considers family history alongside other personal and medical factors. The goal is not to predict with certainty whether someone will develop cancer. Instead, risk assessment helps determine whether standard screening is appropriate or whether additional assessment, surveillance, genetic counselling or other options should be considered.
What Was Fraboc?
Fraboc was developed to give Australian GPs and other healthcare professionals a structured way to assess familial breast and ovarian cancer risk.
Rather than simply asking whether someone had a mother, sister or aunt with breast cancer, the assessment looked at the wider pattern of cancer in a family. This could include which relatives had cancer, what type of cancer they had and the age at which they were diagnosed.
That distinction is important because having a relative with cancer does not automatically mean that a person has a hereditary cancer syndrome. Cancer is common, and many families will have one or more cancer diagnoses without having an inherited cancer-causing gene.
A structured family-history assessment helps separate ordinary family occurrence from patterns that may suggest a higher inherited risk.
Is Fraboc Still Available in Australia?
No. Fraboc has been retired, so people searching for a current Fraboc calculator may encounter old documents, references or outdated information.
Its retirement does not mean that family-history assessment is no longer important. Instead, breast cancer risk assessment has developed to consider a wider range of factors.
Australian cancer-care guidance currently identifies iPrevent, IBIS and CanRisk among validated computerised breast-cancer risk assessment tools. iPrevent is particularly relevant in Australia because it connects risk assessment with risk-management guidance.
This means that if you have found the term Fraboc in an older medical document or online article, you should not assume that you need to find an old version of the tool. A GP or qualified health professional can explain which current assessment is appropriate.
What Replaced Fraboc?
One of the important modern tools used for breast-cancer risk assessment in Australia is iPrevent.
Unlike a simple family-history checklist, modern risk assessment can incorporate multiple factors. Depending on the tool and the person’s circumstances, these may include family history, previous breast conditions, breast density, reproductive or hormonal factors, and other relevant information.
The reason for this broader approach is straightforward: cancer risk is not determined by one factor.
Cancer Council Australia notes that breast-cancer risk can be influenced by age, family history, genetics, previous breast disease, hormonal factors and other characteristics. Breast density is also an important risk factor and can affect how easily cancer is detected on mammography.
Modern tools therefore aim to provide a more complete picture than an assessment based only on family history.
Why Does Family History Matter?
Family history can provide clues about whether cancer risk may be higher than average.
Cancer Council Australia recommends looking at both the mother’s and father’s sides of the family when considering family cancer history. Important clues can include several blood relatives with breast, ovarian or certain other cancers, particularly when cancers occurred at younger-than-usual ages.
For example, a pattern involving several close relatives with breast or ovarian cancer can be more significant than a single diagnosis in an older relative.
The age at diagnosis can also matter. When several relatives develop relevant cancers at unusually young ages, a healthcare professional may consider whether an inherited genetic factor could be involved.
However, family history is not a diagnosis. Even families with a known inherited gene change do not necessarily mean that every family member will develop cancer.
Does One Relative With Breast Cancer Mean You Are High Risk?
Usually, one relative with breast cancer does not automatically mean that you are at high risk.
Breast cancer is relatively common, so individual cases can occur within families without being caused by an inherited cancer syndrome. What matters is the overall pattern.
A GP may want to know whether there are multiple affected relatives, whether they are closely related to you, their ages when diagnosed and whether ovarian or other related cancers have occurred in the family.
Cancer Council Australia also explains that most cancer occurs in people without a family history, while only a small proportion of cancers are associated with inherited faulty genes.
This is why a family history should be assessed rather than interpreted from one detail alone.
Your Father’s Side of the Family Matters Too
One of the most commonly overlooked parts of family-history assessment is the father’s side.
People often think about their mother, grandmother, sisters or aunts when considering breast cancer risk. However, inherited gene changes can come from either parent.
Cancer Council Australia specifically recommends considering cancer history on both sides of the family.
For this reason, a useful family-history record should include relatives from both your maternal and paternal families.
If you do not know the details, you do not need to guess. Tell your GP what you know and what information is uncertain. Your healthcare professional can decide whether additional information or specialist assessment is appropriate.
What Is BRCA1 and BRCA2?
BRCA1 and BRCA2 are genes involved in hereditary breast and ovarian cancer risk.
Some inherited changes in these genes can substantially increase the risk of certain cancers. Cancer Council Australia estimates that around 5% of breast and ovarian cancers are associated with an inherited faulty gene, although the exact proportion varies by cancer type and population.
A BRCA-related risk is different from simply having a relative who had breast cancer. Genetic testing is generally considered when someone’s personal or family history suggests an increased likelihood of an inherited gene change.
Cancer Council Australia states that genetic testing is usually offered when someone is considered at increased risk because of factors such as a strong family history or age at diagnosis.
Genetic testing should therefore be discussed with a qualified healthcare professional rather than interpreted from an online calculator alone.
Understanding Breast Cancer Risk Categories
Australian cancer guidance commonly describes breast cancer risk in relation to population risk.
The broad framework includes:
Average risk: less than 1.5 times the population risk.
Moderate risk: around 1.5 to 3 times the population risk.
High risk: more than 3 times the population risk.
These categories are useful because they can help healthcare professionals decide whether standard screening is appropriate or whether additional risk-management strategies should be discussed.
Importantly, a risk category does not mean that cancer will definitely occur. It describes the estimated probability of developing cancer compared with the population.
Risk can also change over time as a person’s age, medical history or family history changes.
What Information Is Useful for a Risk Assessment?
Before speaking with a GP about family cancer history, it can be helpful to collect whatever information is reasonably available.
Useful details include the names or relationships of relatives who had cancer, the type of cancer they had and approximately how old they were when diagnosed.
It can also help to know whether anyone in the family has previously undergone genetic testing and whether a specific gene change was identified.
You do not need to create a perfect family tree. Even incomplete information can give a GP a starting point for discussion.
If a relative has a genetic-test report, the actual report can be much more useful than a verbal description such as “they tested positive.”
Fraboc vs Modern Risk Assessment
The main difference between Fraboc and newer approaches is the breadth of information considered.
Fraboc focused strongly on familial breast and ovarian cancer patterns. Modern tools such as iPrevent are designed to provide a broader individual risk assessment.
Current Australian guidance lists iPrevent, IBIS and CanRisk as validated breast-cancer risk assessment tools. iPrevent is designed for self-administration by women as well as collaborative use with clinicians and links risk assessment to relevant management guidelines.
This development reflects a simple medical principle: a person’s cancer risk is influenced by multiple factors, not family history alone.
Breast Density and Cancer Risk
Mammographic tissue density is another factor considered in modern breast-cancer risk assessment.
Breast density refers to the amount of fibroglandular tissue visible on a mammogram. It cannot normally be determined simply by feeling the breast.
Higher breast density is associated with increased breast-cancer risk and can also make some cancers harder to see on mammograms.
This is one reason newer risk-assessment approaches can be more comprehensive than older family-history-only assessments.
If a mammogram report contains information about breast density, it may be relevant when discussing your overall risk with your healthcare professional.
What About Ovarian Cancer Risk?
Family history is also relevant to ovarian cancer, particularly when several relatives have had ovarian or related cancers.
However, breast and ovarian cancer should not be treated as exactly the same condition. Current Australian guidance states that there is no effective population-based screening test for ovarian cancer.
For someone with a significant family history of ovarian cancer, the appropriate approach is usually an individual discussion with a doctor about risk, genetic assessment and available management options.
This is particularly important when a family has a known BRCA1 or BRCA2 gene change.
What Happens If Risk Is Higher Than Average?
A higher estimated risk does not automatically mean that cancer is present.
Instead, it can lead to a discussion about appropriate prevention and early-detection strategies.
Depending on the person’s individual circumstances, healthcare professionals may recommend different screening approaches, specialist referral, genetic counselling or risk-reducing strategies.
For women at increased breast-cancer risk, Australian guidance notes that risk-reducing medication can be considered in appropriate circumstances, while women at very high risk may discuss other options with specialist teams.
The important point is that these decisions are individual. A risk calculator should support a medical conversation rather than replace it.
What Screening Is Available in Australia?
BreastScreen Australia provides population-based mammographic screening. Cancer Council Australia’s current guidance states that BreastScreen Australia targets asymptomatic women aged 50 to 74 for screening every two years, while women over 40 can attend on request.
People with substantially increased risk may require a different approach based on their individual circumstances.
That is why knowing your risk can be useful. Screening recommendations for someone at average population risk may not be the same as recommendations for someone with a strong hereditary cancer risk.
If you notice a new or unusual breast change, screening programs are not a substitute for seeing a doctor. Cancer Council Australia recommends medical assessment for changes such as a new lump, unusual thickening, changes in breast shape or size, nipple changes or unusual skin changes.
When Should You Talk to a GP?
Consider discussing your family history with a GP if several relatives have had breast or ovarian cancer, particularly on the same side of the family.
A conversation can also be important when cancer occurred at an unusually young age, when a male relative has had breast cancer, or when genetic testing has identified a relevant inherited gene change in the family.
You do not have to wait until you have symptoms. Risk assessment is about understanding future risk and choosing appropriate prevention or early-detection strategies.
If you are simply unsure whether your family history is important, that uncertainty itself is a reasonable reason to ask your GP.
The Bottom Line
Fraboc was an important Australian approach to understanding familial breast and ovarian cancer risk, but the tool itself is no longer active. Its central idea remains highly relevant: family history should be collected carefully and interpreted in context.
Today, tools such as iPrevent provide a broader assessment by considering family history alongside other personal risk factors. The result is not a diagnosis and cannot guarantee what will happen in the future. Instead, it can help healthcare professionals decide whether someone is at average, moderate or high risk and whether additional management should be considered.
If breast or ovarian cancer appears repeatedly in your family, particularly at younger ages, speak with a GP. Bring whatever family-history information you have from both sides of the family and mention any known genetic-test results.
Understanding your risk is not about assuming the worst. It is about replacing uncertainty with reliable information and making screening or prevention decisions based on evidence.

FAQs
Is Fraboc still available?
No. Fraboc is a retired Australian clinical risk-assessment tool. Current breast-cancer risk assessment can use newer validated tools such as iPrevent, IBIS and CanRisk.
What does Fraboc stand for?
Fraboc stands for Familial Risk Assessment – Breast and Ovarian Cancer. It was designed to help health professionals assess familial breast and ovarian cancer risk.
What replaced Fraboc?
Modern Australian practice uses newer risk-assessment approaches, including iPrevent. iPrevent considers a broader range of risk factors and links risk assessment with management guidance.
Does having a mother with breast cancer mean I will get breast cancer?
No. Having a close relative with breast cancer can increase risk, but it does not mean that you will definitely develop cancer. The overall family pattern, ages at diagnosis, genetic factors and other personal risk factors matter.
Does my father’s family history matter?
Yes. Family history should be considered on both the maternal and paternal sides because inherited gene changes can come from either parent.
Can genetic testing tell me whether I will get cancer?
Genetic testing can identify certain inherited gene changes associated with increased cancer risk, but it cannot provide certainty that someone will or will not develop cancer. Testing is generally considered when personal or family history suggests an increased likelihood of an inherited risk.
Is there a screening test for ovarian cancer?
There is currently no effective population-based screening test for ovarian cancer in Australia. People with a significant family history should discuss their individual risk and options with a doctor.
