Myth: If the gene mutation BRCA1 or BRCA2 is detected in your DNA, you will definitely develop breast cancer
Here’s The Truth
According to the Centers for Disease Control and Prevention (CDC): “Not every woman who has a BRCA1 or BRCA2 gene mutation will get breast or ovarian cancer, but having a gene mutation puts you at an increased risk for these cancers. About 50 out of 100 women with a BRCA1 or BRCA2 gene mutation will get breast cancer by the time they turn 70 years old.”
For people who discover they have a BRCA1 or BRCA2 gene mutation, there are various proactive measures that can be done to reduce the risk of developing breast cancer, such as taking hormone therapy or various surgical interventions. Talk to your healthcare provider about the options that may be available to you.
