In honor of Breast Cancer Awareness Month, let’s talk about risk assessment!
The Breast Cancer Risk Assessment Tool (BCRAT), also known as The Gail Model, allows health professionals to estimate a woman's risk of developing invasive breast cancer over the next five years and up to age 90 (lifetime risk).
The tool uses a woman's personal medical and reproductive history and the history of breast cancer among her first-degree relatives (mother, sisters, daughters) to estimate absolute breast cancer risk-her chance or probability of developing invasive breast cancer in a defined age interval.
This calculator takes about five minutes to complete. It does not replace a physical exam by your provider, breast imaging or mammography.
Are you at high risk? You can input all your information at the following link.
Enter the required information to calculate a patient's absolute risk for developing breast cancer. Created by the scientist at the National Cancer Institute and the NSABP.
