Breast cancer is one of the most common cancers affecting women worldwide, and while lifestyle and environmental factors play a role, genetics can significantly influence a person's risk. One of the most frequently asked questions is: Is there a genetic link to breast cancer? The answer is yes — in many cases, genetics can be a major contributing factor.
Understanding the Genetic Risk
Approximately 5% to 10% of breast cancer cases are believed to be hereditary. This means they are caused by abnormal genes passed from parents to children. The most well-known genetic mutations associated with breast cancer are in the BRCA1 and BRCA2 genes. Women who inherit mutations in these genes have a much higher risk of developing breast and ovarian cancer compared to the general population. In fact, a woman with a BRCA mutation has up to a 70% chance of developing breast cancer by the age of 80.
But BRCA isn’t the only gene involved. Other less common mutations — such as TP53, PTEN, and PALB2 — can also increase breast cancer risk. Genetic counseling and testing can help individuals understand their risk and make informed decisions about screening and preventive measures.
Who Should Consider Genetic Testing?
You might consider genetic testing if:
-
You have multiple family members who have had breast or ovarian cancer.
-
A family member was diagnosed with breast cancer before age 50.
-
A male in your family was diagnosed with breast cancer.
-
You have Ashkenazi Jewish heritage (as BRCA mutations are more common in this group).
If you fall into any of these categories, it’s important to speak with a qualified healthcare provider.
