Genetic Testing and Counseling for Loved Ones
When someone in your family has breast cancer, especially at a young age, it may not just be their fight.
They may carry a genetic mutation (like BRCA1 or BRCA2) that increases the risk for breast, ovarian, and other cancers; and these mutations can be passed down. If you’re a blood relative (parent, sibling, child, cousin, etc.), you may have inherited the same mutation. Knowing your own risk can help you take preventive steps, earlier.
What is genetic testing?
Genetic testing looks at your DNA to see if there are any inherited changes in specific genes that could raise your risk for cancer.
It usually involves giving a blood or saliva sample, which is sent to a lab. The results are shared with your doctor and a genetic counselor, who can help you understand what they mean and what your options might be.

Genetic Testing: Weighing the Benefits and Limitations
Genetic testing can offer powerful insights, but it also comes with emotional and practical considerations. Understanding both the potential benefits and limitations can help you make the decision that’s right for you and your family.
What are the benefits?
Clarity about your risk
If you test positive for a known gene mutation (like BRCA1 or BRCA2), you’ll gain a clearer picture of your personal risk for breast, ovarian, and related cancers.
Proactive health planning
With this information, you and your doctor can explore options for earlier screenings, risk-reducing medications, or preventive surgeries. It’s a chance to stay one step ahead.
Eligibility for research or prevention trials
Some people with inherited mutations may qualify for clinical studies focused on cancer prevention or early detection, helping both themselves and future generations.
A ripple effect for your family
Your test results could also help other family members understand and manage their own risk.
What are the Limitations?
Emotional weight
Learning about a higher cancer risk can be unsettling, especially when the information is new. Some people may find it overwhelming at first, and that’s completely normal.
Not a crystal ball
Testing can’t tell you if, or when, you’ll get cancer. And not everyone with a mutation actually develops the disease. It’s about risk, not certainty.
Complex implications for family
Because gene mutations are inherited, your results could have meaning for your parents, siblings, or children. It’s something to consider before testing—and discuss with a healthcare provider.
No substitute for screening
Genetic testing can’t detect cancer itself. It’s one tool, used alongside other important steps like mammograms or clinical exams.
What Happens at a Genetic Counseling Appointment
Your genetic counselor will start by asking about your personal and family history, especially patterns that might suggest an inherited risk, such as:
- Cancer diagnosed at a young age
- Several family members with cancer
- Family members who’ve had more than one kind of cancer
They’ll talk with you about:
- Whether testing makes sense for you right now
- What kinds of results you might receive
- How results might affect your medical decisions or your family
- Concerns like cost, insurance coverage, or privacy
Together, you’ll decide what feels right for you, whether that means testing now, waiting, or choosing not to test.
What should I bring to my appointment?
It helps to gather as much information as you can about your family’s health history, including:
- Who in your family has had cancer, what kind, and at what age
- Any pre-cancer diagnoses or known genetic mutations
- Medical reports, if available, like pathology or surgery summaries
- Any previous genetic test results from yourself or relatives
The more complete your information, the better your counselor can understand your potential risk.
Genetic test results can sometimes raise new questions or emotions. A genetic counselor can walk you through what your results mean for you and possibly for your family. Together, you can make informed, confident choices about next steps.
