Genetic testing can be a powerful tool in the fight against hereditary breast cancer—but it’s also surrounded by confusion. Many patients wonder: How accurate is genetic testing for breast cancer? Is the BRCA (BReast CAncer) mutation a guarantee that you’ll develop cancer? Can it skip a generation? And is it only a concern for women?
At Bedford Breast Center, we offer BRCA genetic testing to help people make empowered, proactive decisions about their breast health. In this post, we’ll break down seven common misconceptions to help you better understand who should consider genetic testing and what the results really mean.
1. Myth: If you have a BRCA mutation, you will get breast cancer.
Fact: A BRCA mutation increases your risk but doesn’t guarantee a diagnosis.
BRCA1 and BRCA2 mutations are linked to a higher risk of breast and ovarian cancer, but not everyone with the mutation develops cancer. According to the National Cancer Institute, the lifetime risk of breast cancer in BRCA1 carriers is around 55% to 72%. While that’s significant, it also means many people with the mutation do not develop cancer. That’s why regular screening and early interventions are key.
2. Myth: BRCA mutations only affect women.
Fact: Men can carry BRCA mutations, pass them on, and face cancer (even breast cancer) risk themselves.
While most conversations around BRCA focus on women, men with these mutations are at risk for prostate, pancreatic, and male breast cancer. They can also pass the mutation to their children—just like women can. That’s why BRCA genetic testing is an important option for both men and women with a family history of cancer.
3. Myth: BRCA mutations can “skip” a generation.
Fact: BRCA mutations do not skip generations—only the diagnosis might.
Genetic mutations are passed directly from parent to child, so if a parent has the BRCA mutation, there’s a 50% chance their child will inherit it. However, if a parent carried the gene but never developed cancer, it might appear as though the mutation skipped a generation. This underscores the importance of looking at extended family history, not just diagnosed cases.
4. Myth: BRCA mutations are rare.
Fact: They’re more common than many people realize—especially in some populations.
Roughly 1 in 400 people carry a BRCA mutation. For certain groups, like individuals of Ashkenazi Jewish descent, that number jumps to about 1 in 40. When it comes to who should get genetic testing for breast cancer, you might be surprised to learn how often a hereditary link is found.
5. Myth: You only need genetic testing if your mother had breast cancer.
Fact: Family history on either side can raise your risk.
Many people overlook the father’s side of the family when assessing cancer risk. However, BRCA mutations are inherited from either parent. If your father’s family has a strong history of breast, ovarian, pancreatic, or prostate cancer, you should consider exploring genetic testing options.
6. Myth: Men can’t pass on BRCA mutations.
Fact: Men are just as likely as women to pass BRCA mutations to their children.
Each child of a BRCA-positive parent—regardless of that parent’s gender—has a 50% chance of inheriting the mutation. It’s not uncommon for a daughter to inherit the mutation from her father, even if he never developed cancer himself.
7. Myth: Genetic testing is confusing and time-consuming.
Fact: Testing is simple, highly accurate, and results arrive within a few weeks.
Wondering how long does BRCA genetic testing take? In most cases, results are available within 2 to 4 weeks. At Bedford Breast Center, we guide you through the entire process—from understanding “What is BRCA genetic testing?” to reviewing your results with one of our breast specialists.
Is Genetic Testing for Breast Cancer Worth It?
For many, the answer is yes. It provides peace of mind, empowers prevention, and helps you take greater control of your health. If you’re considering BRCA genetic testing, contact Bedford Breast Center at (310) 278-8590 or request a consultation using the online form.
