What is the breast cancer risk calculator recommended by Olivia Munn?

Olivia Munn's breast cancer diagnosis is drawing attention to a frequently used breast cancer risk calculator. The actor says her score prompted further tests and the discovery of an aggressive form of the disease. The Breast Cancer Risk Assessment Tool is a questionnaire on the National Cancer Institute website. It's designed for health care providers to use with patients and can help guide decisions about screening. It was originally based on data from only white women. Updates have made it more accurate for Black, Hispanic and Asian and Pacific Islander women.
