At MKGenetix, we know that conversations about breast cancer can stir up many emotions such as fear, confusion, and sometimes even guilt. October is Breast Cancer Awareness Month, a time dedicated to education, prevention, and empowerment. But while pink ribbons and screenings get a lot of attention (and rightfully so), one topic still causes uncertainty for many families is about the value of genetic counseling and genetic testing.
In this post, we’ll unpack what breast cancer genetic testing really involves, who should consider it, and how a genetic counselor can help you make sense of your results—so you can move forward with clarity and confidence.
What Is Breast Cancer Genetic Testing?
Most people have heard of BRCA1 and BRCA2, the two genes most famously linked to hereditary breast and ovarian cancer. But the story doesn’t stop there because these two genes only explain about half of those with a hereditary (inherited) increased risk for breast cancer.
Today’s testing can look at dozens of genes that influence breast cancer risk, including PALB2, CHEK2, ATM, TP53, and others. Identifying a change in one of these genes that disrupts how the gene functions can help individuals and families take proactive steps. This could mean earlier mammograms, MRI screening, medications that lower risk, or preventive surgeries.
Genetic testing is available for those with a strong family history but also other reasons such as:
- Anyone diagnosed with breast cancer under age 50
- Those with triple-negative breast cancer diagnosed under age 60
- People with multiple relatives (on the same side of the family) who’ve had breast, ovarian, prostate, or pancreatic cancer
- Men diagnosed with breast cancer (yes, it happens)
- Individuals of Ashkenazi Jewish ancestry
- Anyone with a known genetic change increasing the chance for cancer in the family
Why Knowledge Is Power
Understanding your genetic background doesn’t mean you have to take drastic steps. Instead, it means you get to make informed choices.
For some, testing offers answers after years of uncertainty about “why” cancer runs in the family. For others, it provides peace of mind when results show someone is NOT at an increased risk for the cancers in the family. Either way, it allows you and your care team to tailor prevention and screening to you, not just the general population.
Common Misconceptions About Genetic Testing
Many people still avoid testing because of myths like:
- “I don’t have a family history, so I don’t need it.”
- “If I test positive, my insurance will drop me.”
- “It’s too expensive.”
In truth, family history alone doesn’t always predict risk, federal law (GINA) protects against health insurance discrimination, and many labs offer low-cost options (less than $250) depending on insurance coverage. Genetic counselors can clarify these concerns and help you access appropriate, affordable testing.
How Genetic Counseling Can Help
At MKGenetix, our approach is simple: information should empower, not overwhelm.
When it comes to hereditary breast cancer, we help by:
- Assessing personal and family history to determine whether testing is appropriate
- Explaining test options—from targeted BRCA analysis to multi-gene panels
- Interpreting results clearly (because “variant of uncertain significance” shouldn’t sound like a riddle)
- Providing support for next steps, including family communication, screening plans, and referrals to oncology teams
You’re Not Alone
Whether you’re newly diagnosed, have a strong family history, or are simply curious about your risk, you don’t have to navigate this alone.
Genetic information can be emotional—but it can also be life-saving. And sometimes, the most empowering step you can take this Breast Cancer Awareness Month isn’t buying something pink—it’s asking the right questions about your health.
