FRABOC, also written as FRA-BOC, stands for Familial Risk Assessment – Breast and Ovarian Cancer. It was an Australian tool used by health professionals to understand a woman’s breast and ovarian cancer risk based on her family history.
People may still see the name FRABOC in old medical records, referral letters, or health documents. The original FRABOC tool is no longer available through Cancer Australia.
This guide explains what FRABOC was, how it worked, its risk groups, and what family information it used. It also explains newer tools such as iPrevent.
What Is FRABOC?
FRABOC was an online clinical tool used in Australia. It helped health professionals understand possible breast and ovarian cancer risk based mainly on family history.
The tool looked at cancer cases within a person’s family. It considered which relatives had cancer, what type of cancer they had, and their age when they were diagnosed.
FRABOC was mainly made for GPs, nurses, and other health professionals. It was not a home cancer test.
The tool placed people into broad risk groups. These groups helped doctors decide whether normal care was enough or whether more assessment might be needed.
FRABOC could only estimate risk. It could not tell for certain whether someone would develop cancer.
What Does FRABOC Stand For?
FRABOC stands for Familial Risk Assessment – Breast and Ovarian Cancer.
The name has two main parts:
FRA means Familial Risk Assessment.
BOC means Breast and Ovarian Cancer.
The word “familial” means related to a family. FRABOC looked for patterns of breast and ovarian cancer within families.
The name may also appear as FRA-BOC in older health documents.
Why Was FRABOC Developed?
Family cancer history can be difficult to understand.
Having one relative with breast cancer does not always mean a person has a high inherited cancer risk. Doctors need to look at the full family history.
They may look at how many relatives had cancer, what type of cancer they had, and how old they were when diagnosed. They may also look at which side of the family was affected.
FRABOC gave health professionals a simple and organized way to review this information.
The result could help them decide whether normal care was suitable or whether the person needed more assessment.
How Did FRABOC Work?
A health professional collected information about cancer in the person’s family.
Information from both the mother’s and father’s sides was important. The doctor or nurse could look at which relatives had cancer, how they were related to the person, the type of cancer, and their age at diagnosis.
FRABOC then placed the person into one of three broad risk groups:
- At or slightly above average risk
- Moderately increased risk
- Potentially high risk
These groups helped health professionals decide whether more assessment might be useful.
FRABOC did not give a certain answer about whether someone would develop cancer. It only estimated risk using the available family information.
What Family History Did FRABOC Consider?
FRABOC looked at different parts of a person’s family cancer history.
First-degree relatives include parents, brothers, sisters, and children.
Second-degree relatives can include grandparents, aunts, uncles, nieces, nephews, and grandchildren.
Doctors could also look at the type of cancer and the person’s age when the cancer was found.
Some family patterns could need closer attention. These included several relatives with breast or ovarian cancer, cancer at a young age, male breast cancer, or cancer in both breasts.
Breast and ovarian cancer appearing in the same family could also be important.
A known cancer-related genetic change in the family could also affect the assessment.
However, family history alone could not prove that someone had inherited a cancer-related genetic change.
Why the Father’s Side of the Family Matters
Cancer history on the father’s side is also important.
Some cancer-related genetic changes can be passed down from either the mother or father.
For example, a father may carry a genetic change and pass it to his children even if he has never had breast cancer.
For this reason, a family cancer risk assessment should look at both sides of the family.
FRABOC Risk Categories
FRABOC used three broad groups to describe family-related breast cancer risk.
These were:
- At or slightly above average risk
- Moderately increased risk
- Potentially high risk
These groups helped doctors decide whether more assessment might be needed.
They were not cancer diagnoses. A higher risk group did not mean a person had cancer or would definitely develop it.
At or Slightly Above Average Risk
This was the lowest FRABOC risk group.
Most women assessed under the old system were expected to be in this group.
It generally meant the family history did not show strong signs of increased inherited cancer risk.
However, it did not mean the person could never develop breast cancer. People without a strong family history can still develop the disease.
Moderately Increased Risk
This group meant the person’s estimated family-related risk was higher than average.
For example, doctors might pay more attention when a close relative developed breast cancer at a younger age or when several relatives were affected.
The whole family history still needed to be considered.
Being in this group did not mean the person would definitely develop cancer.
Potentially High Risk
This was the highest FRABOC risk group.
A stronger family pattern could lead to this category. Examples could include several relatives with cancer, breast cancer at a very young age, male breast cancer, or breast and ovarian cancer in the same family.
A known inherited cancer-related genetic change could also be important.
This result did not mean the person had cancer. It could mean that more detailed assessment was needed.
How FRABOC Considered Breast and Ovarian Cancer
FRABOC looked at breast cancer patterns within a family.
Doctors considered how many relatives had breast cancer and how closely they were related to the person. They also looked at their ages when cancer was diagnosed.
Breast cancer at a younger age could sometimes be more important when looking for possible inherited risk.
Male breast cancer and cancer affecting both breasts could also receive more attention.
Ovarian cancer was also part of the FRABOC assessment. Doctors could look at whether ovarian cancer appeared together with breast cancer in the same family.
However, these family patterns alone could not prove that an inherited cancer condition was present. More medical or genetic assessment could be needed.
Was FRABOC a Cancer Test?
No. FRABOC was not a cancer test.
It was not a mammogram, ultrasound, biopsy, blood test, or scan. It could not tell whether someone currently had breast or ovarian cancer.
FRABOC only estimated family-related cancer risk.
A cancer test looks for signs of cancer that may already be present. A risk assessment looks at the chance of developing cancer.
A higher FRABOC risk result did not mean the person had cancer. A lower result also did not mean the person could never develop cancer.
Was FRABOC a Genetic or BRCA Test?
No. FRABOC was not a genetic test.
It did not examine a person’s DNA.
BRCA1 and BRCA2 are genes. Certain harmful changes in these genes can increase the risk of breast, ovarian, and some other cancers.
FRABOC looked at family cancer patterns. BRCA testing looks directly at DNA.
FRABOC could not tell whether someone had a BRCA1, BRCA2, or another cancer-related genetic change.
However, a strong family cancer history could lead a doctor to consider genetic counselling or genetic testing.
What Happened After a Higher FRABOC Risk Result?
A higher FRABOC result did not mean that treatment was automatically needed.
Instead, it helped doctors decide whether the person needed more assessment.
A doctor might review the family history in more detail or refer the person to a family cancer service.
Genetic counselling could also be discussed. Genetic testing might be considered when suitable.
Doctors could also discuss screening and other ways to manage risk.
The next step depended on the person’s family history and individual situation.
Is FRABOC Still Available?
No. The original FRABOC tool is no longer available through Cancer Australia.
This is why people may find old documents instead of a working FRABOC calculator when searching online.
The name can still appear in old GP letters, medical records, referral forms, PDFs, and health documents.
These are old references.
People should not use an old FRABOC result to work out their current cancer risk. Newer assessment methods are now available.
What If FRABOC Appears in an Old Medical Record?
Seeing FRABOC in an old medical record does not mean that you had cancer.
It may simply mean that a doctor assessed or discussed your family history of breast and ovarian cancer.
The record may include an old risk group, information about family members, or a recommendation for further assessment.
An old result may still be useful as part of your medical history. However, it may not show your current risk.
Family information can change over time. New cancer cases or genetic test results may become available.
If an old FRABOC result is still important to you, discuss it with a healthcare professional using your current family and medical information.
What Replaced FRABOC?
Newer cancer risk assessment tools are now available.
One important Australian tool is iPrevent. It gives a more personal breast cancer risk assessment.
Other tools include CanRisk and IBIS, also called the Tyrer-Cuzick model.
These are not simply new names for FRABOC. They use different methods and can consider more information.
They can give more detailed risk estimates, but they still cannot say for certain whether someone will develop cancer.
What Is iPrevent?
iPrevent is a modern breast cancer risk assessment and risk-management tool linked with the Peter MacCallum Cancer Centre in Australia.
It can look at family history together with other information about the person.
This may include personal and medical information, reproductive history, hormone-related factors, breast health information, and lifestyle factors.
Because it uses more information, iPrevent can give a more personal risk estimate than the three broad groups used by FRABOC.
It can also help support discussions about screening and ways to manage breast cancer risk.
iPrevent is still a risk assessment tool. It cannot diagnose breast cancer or guarantee whether someone will develop it.
FRABOC vs iPrevent
FRABOC and iPrevent both help with cancer risk assessment, but they work differently.
| Feature | FRABOC | iPrevent |
|---|---|---|
| Status | Old tool; no longer available through Cancer Australia | Modern risk assessment tool |
| Main focus | Family breast and ovarian cancer patterns | Personal breast cancer risk |
| Family history | Yes | Yes |
| Other personal factors | Limited | Can include more personal and medical factors |
| Result | Broad risk group | More personal risk estimate |
| Diagnoses cancer | No | No |
| Genetic test | No | No |
| Main use | Helped guide further assessment | Helps support risk and management discussions |
FRABOC mainly used family history and broad risk groups.
iPrevent can use more information to give a more personal risk estimate.
Other Modern Risk Assessment Tools
Other tools can also help estimate breast or inherited cancer risk.
They are separate tools and do not work exactly like FRABOC.
CanRisk
CanRisk is an online cancer risk assessment tool based on BOADICEA models.
It can use detailed family history, genetic information, and other risk factors.
This allows CanRisk to give more detailed estimates than FRABOC’s broad risk groups.
It can be useful when a more detailed family or genetic risk assessment is needed.
IBIS / Tyrer-Cuzick
IBIS, also known as the Tyrer-Cuzick model, is another breast cancer risk model.
It can look at family history together with other personal and reproductive information.
It can provide a more personal breast cancer risk estimate than the old FRABOC system.
IBIS is a separate tool with its own method. It is not another name for FRABOC.
How to Prepare for a Current Family Cancer Risk Assessment
Try to collect useful family cancer information before speaking with a healthcare professional.
Useful details include:
- Which relatives had cancer.
- How they are related to you.
- What type of cancer they had.
- Their age when diagnosed.
- Whether they are from your mother’s or father’s side.
- Whether anyone had cancer in both breasts.
- Whether a male relative had breast cancer.
- Whether someone had more than one cancer.
- Whether anyone had genetic testing.
- Whether a known inherited genetic change was found.
If a relative had genetic testing, bring a copy of the result if possible.
Do not worry if you cannot find every detail. Tell the healthcare professional what you know and explain which information is uncertain.
Common Misunderstandings About FRABOC
FRABOC is sometimes misunderstood because people still find the name in old medical documents.
FRABOC was not a cancer test. It only helped estimate family-related cancer risk.
It was also not a BRCA or genetic test. It did not examine DNA.
A high FRABOC risk group did not mean a person definitely had cancer or would develop it.
A lower risk group also did not mean there was no chance of cancer.
Having one relative with breast cancer did not automatically mean someone was at high risk. Doctors looked at the full family history.
The father’s side of the family was also important.
FRABOC should not be used today as a self-assessment calculator. Current risk assessments should use modern tools and medical guidance.
Why FRABOC Still Matters
FRABOC is mainly useful today for understanding older Australian medical records and cancer risk assessments.
People may still see the term in old referral letters, medical records, PDFs, or health documents.
The main idea behind FRABOC is still important. Family cancer history can help doctors understand whether someone may need more assessment.
However, FRABOC itself is an old tool. Current health decisions should use newer information, modern risk assessment methods, and professional medical advice.
Bottom Line
FRABOC stands for Familial Risk Assessment – Breast and Ovarian Cancer. It was an Australian tool used by health professionals to assess family patterns of breast and ovarian cancer.
It used three broad groups: at or slightly above average risk, moderately increased risk, and potentially high risk.
FRABOC was not a cancer test or genetic test. It could not diagnose cancer or identify BRCA genetic changes.
The original FRABOC tool is no longer available through Cancer Australia. Newer tools such as iPrevent, CanRisk, and IBIS can provide more detailed risk estimates.
People who are concerned about their current cancer risk should use current medical guidance rather than relying on an old FRABOC result.
