5 Red Flags in Your Family Tree That May Mean You Should Consider a BRCA Test
Quick Answer
A strong family history of certain cancers may indicate an increased likelihood of an inherited BRCA1 or BRCA2 gene mutation. Five important family-history red flags include:
Several relatives with breast cancer
Breast cancer diagnosed at a younger age
Ovarian or related cancers in the family
Male breast cancer
Breast cancer affecting both breasts or a known BRCA mutation in the family
These patterns do not mean that you have a BRCA mutation or that you will develop cancer. However, they may be reasons to discuss genetic counselling and BRCA testing with a qualified healthcare professional.
If your family history suggests hereditary cancer risk, a hereditary breast cancer blood test can help assess whether specific inherited genetic changes associated with breast cancer risk are present.
What Is a BRCA Test?
A BRCA test is a type of genetic test that looks for inherited changes, or variants, in the BRCA1 and BRCA2 genes.
These genes normally help protect cells from developing cancer. Certain inherited harmful variants can increase the risk of breast, ovarian and some other cancers.
A BRCA test is therefore different from a routine blood test used to check for an existing illness.
It is primarily used to help assess inherited cancer risk.
If you have a strong family history of breast or related cancers, genetic testing may provide additional information that can help guide conversations with your healthcare team about screening and risk management.
5 Family History Red Flags That May Suggest BRCA Testing
Not everyone with a family history of breast cancer has an inherited BRCA mutation. However, certain patterns can make hereditary cancer risk more relevant.
Here are five family-history red flags worth discussing with a healthcare professional.
1. Several Relatives Have Had Breast Cancer
If multiple people in your family have been diagnosed with breast cancer, particularly close blood relatives, it may be worth discussing your family history with a healthcare professional.
For example, a pattern involving a mother, sister, daughter, grandmother, aunt or other close relatives may provide useful information when assessing hereditary cancer risk.
The number of relatives, their relationship to you and the age at which they were diagnosed all matter.
A family history does not automatically mean that you have a BRCA mutation. Genetic counselling can help determine whether genetic testing may be appropriate.
2. Breast Cancer Occurred at a Young Age
Breast cancer diagnosed at a relatively young age can be one of the patterns considered when assessing hereditary breast cancer risk.
If a close relative developed breast cancer before age 50, particularly alongside other cases of breast or ovarian cancer in the family, it may be important to discuss this history with a healthcare professional.
You should record:
Who in your family had breast cancer
Their relationship to you
Their age when diagnosed
Whether cancer affected one or both breasts
Whether other cancers occurred in the family
This information can help create a clearer picture of your family's cancer history.
3. Ovarian Cancer Is Present in Your Family
A family history of ovarian cancer can also be relevant when assessing the possibility of hereditary breast and ovarian cancer.
BRCA1 and BRCA2 mutations are associated with increased risks for several cancers, including breast and ovarian cancer.
For this reason, a family history that includes both breast and ovarian cancer may warrant further discussion about genetic counselling and testing.
If a relative has had ovarian cancer, make sure to include this information when discussing your family history with your healthcare provider.
4. A Male Relative Has Had Breast Cancer
Male breast cancer is uncommon.
When breast cancer occurs in a male relative, it can be an important part of the family history when evaluating hereditary breast cancer risk.
This is particularly relevant if other relatives have also had breast, ovarian or related cancers.
Both women and men can inherit BRCA mutations and pass them to their children.
Therefore, a family history of cancer should not be considered only through the women in your family.
Does Breast Cancer Risk Come From Your Father's Side?
Yes,This is an important point that is sometimes overlooked.
BRCA1 and BRCA2 mutations can be inherited from either parent. Your father's family history can therefore be just as relevant as your mother's when assessing hereditary breast cancer risk.
For example, if your father's mother, sister or other close relatives had breast or ovarian cancer, this information may be relevant when discussing genetic testing.
When preparing your family history, try to look at both sides of your family.
5. Breast Cancer Affected Both Breasts or There Is a Known BRCA Mutation
A history of breast cancer affecting both breasts can be another factor considered during hereditary cancer risk assessment.
Similarly, if a blood relative has already been identified as carrying a harmful BRCA1 or BRCA2 variant, this is particularly important information to share with your healthcare provider.
In some families, genetic testing begins with a relative who has had cancer. If a specific inherited variant is identified, other family members may then be offered targeted testing based on their individual circumstances.
If you already know that a BRCA mutation exists in your family, tell your healthcare provider before undergoing testing.
Can You Have a BRCA Mutation Without a Strong Family History?
Yes,A person can carry an inherited BRCA mutation even when their family history does not appear strongly suggestive of hereditary cancer.
There are several reasons why a family history may not look obvious. For example:
The family may be small.
There may be few female relatives.
Relatives may not know their exact diagnoses.
Family members may have died from other causes before developing cancer.
Previous generations may not have been genetically tested.
Therefore, family history is an important part of risk assessment, but it cannot always identify every person who carries a BRCA mutation.
What Does a BRCA Test Tell You?
Depending on the test and the genes or variants being evaluated, genetic testing can provide different types of results.
Positive Result
A pathogenic or likely pathogenic variant may indicate an increased inherited risk for certain cancers.
It does not mean that you currently have cancer.
Negative Result
A negative result means that the specific genetic changes the test was designed to identify were not detected.
However, a negative BRCA result does not mean that a person has no risk of developing breast cancer.
Variant of Uncertain Significance
Sometimes testing identifies a genetic change whose significance is not yet clear.
This is called a variant of uncertain significance (VUS).
A VUS should not automatically be interpreted as a cancer-causing mutation. Your healthcare professional can explain what the result means in the context of your personal and family history.
BRCA Testing Is Not the Same as Breast Cancer Screening
This distinction is important.
A BRCA genetic test evaluates inherited genetic information associated with cancer risk.
Breast cancer screening, on the other hand, looks for changes in breast tissue that may require further evaluation.
Depending on your age, personal risk and medical history, your healthcare professional may recommend appropriate breast screening.
A BRCA test does not replace mammograms, breast examinations or other screening recommended for you.
Likewise, having a mammogram does not determine whether you carry a BRCA mutation.
They answer different questions.
What Should You Do If You Recognise These Red Flags?
If one or more of these patterns appears in your family history, don't assume that you have a BRCA mutation.
Instead, start by documenting your family history.
Write down:
The type of cancer each relative had
Their age at diagnosis
Their relationship to you
Whether the cancer affected one or both breasts
Any history of ovarian cancer
Any history of male breast cancer
Whether anyone in the family has previously had genetic testing
You can then discuss this information with a qualified healthcare professional or genetic counsellor.
Based on your personal and family history, they can help determine whether genetic testing may be appropriate.
Hereditary Breast Cancer Testing in Dubai and the UAE
For people in Dubai and across the UAE who are concerned about inherited breast cancer risk, genetic testing can be considered as part of a broader risk assessment when clinically appropriate.
A hereditary breast cancer blood test can assess genetic information relevant to hereditary breast cancer risk.
If you are considering testing, it is important to understand what the specific test evaluates and how the results will be interpreted.
Genetic testing is most useful when the results are considered alongside your personal and family history rather than viewed in isolation.
Can a Hereditary Breast Cancer Blood Test Diagnose Breast Cancer?
No.
A hereditary breast cancer blood test is not designed to diagnose whether someone currently has breast cancer.
Instead, genetic testing looks for inherited genetic variants that may be associated with increased cancer risk.
If you have symptoms such as a new breast lump, changes in breast shape or size, nipple changes, unusual discharge or other concerning breast changes, speak with a healthcare professional rather than relying on genetic testing alone.
What Happens After a BRCA Test?
The next step depends on the result and your personal circumstances.
A healthcare professional may consider:
Your genetic test result
Your personal history
Your family's cancer history
Your age
Previous breast or ovarian cancer diagnoses
Other relevant genetic findings
A positive result may lead to discussions about appropriate screening and risk-management options.
A negative result may require interpretation based on whether a known family mutation was being tested for and what type of genetic testing was performed.
This is why genetic test results should be interpreted in context rather than viewed as a simple yes-or-no answer about cancer.
Why Knowing Your Family History Matters
Your family history can provide valuable information about patterns that may otherwise be overlooked.
Knowing whether cancer occurred on your mother's or father's side, the ages at diagnosis and the types of cancer involved can help healthcare professionals assess whether hereditary cancer testing may be appropriate.
You don't need to wait until several relatives have developed cancer before discussing your concerns.
If you are worried about your inherited risk, speaking with a qualified healthcare professional can help you understand your options.
