What Is a Breast Cancer Risk Score—and Do You Need One?
Everyone has a different level of risk for developing breast cancer—but most people don’t know what their personal breast cancer risk score is.
What Is a Breast Cancer Risk Score?
Your breast cancer risk score estimates how likely you are to develop breast cancer based on your health history, family background, and lifestyle. Knowing your score helps you and your doctor decide when to start screening, how often to get checked, and whether you need additional tests like MRI.
Experts recommend finding out your score by age 25 so you can make informed choices about your health.

When her results showed a higher risk, she immediately got a breast MRI as recommended—finding her cancer early and potentially saving her life.
“If I hadn’t taken that risk assessment, I don’t know how long it would’ve been before I found my cancer,” Olivia shared. “It changed everything.”
