BRCA Gene Mutation

Everyone carries the genes called BRCA1 and BRCA2. In their healthy form, they act as protectors, helping repair damaged DNA and keeping cell growth in check. The name BRCA comes from "BReast CAncer," reflecting the genes that researchers identified in the 1990s. When one of these genes carries a harmful change — a mutation — its protective function is weakened, and the lifetime risk of certain cancers rises.

A BRCA Gene Mutation can be passed down from either parent, and each child of a parent who carries one has a chance of inheriting it. People with a BRCA1 or BRCA2 mutation have a notably higher lifetime risk of breast cancer and ovarian cancer, and the mutations are linked to some other cancers as well. Having a mutation does not mean cancer is certain — many people who carry one never develop the disease — but the elevated risk is meaningful enough to plan around.

This is where genetic testing and genetic counseling come in. A simple blood or saliva test can reveal whether you carry a known mutation, and a genetic counselor can help you understand what the results mean for you and your family. Knowing your status opens the door to choices: more frequent and earlier screening, risk-reducing medications, or preventive surgery such as prophylactic mastectomy or removal of the ovaries. These are deeply personal decisions, made with the guidance of a care team who knows your full history.

Knowing whether you carry a BRCA gene mutation can transform vague worry into a concrete, manageable plan. With this knowledge, screening can begin earlier and happen more often, so that if cancer ever does develop, it is far more likely to be caught at an early, treatable stage. It also opens the door to preventive steps that can substantially lower risk.

The information reaches beyond you alone. Because these mutations run in families, learning your status can help your siblings, children, and other relatives understand their own risk and make informed choices. For women with a strong family history of breast or ovarian cancer, this knowledge can be one of the most powerful tools available for taking charge of their health.
