Using Clinical Factors and Mammographic Breast Density to Estimate Breast Cancer Risk: Development and Validation of a New Predictive Model

Background: Current models for assessing breast cancer risk are complex and do not include breast density, a strong risk factor for breast cancer that is routinely reported with mammography. Objective: To develop and validate an easy-to-use breast cancer risk prediction model that includes breast density. Design: Empirical model based on Surveillance, Epidemiology, and End Results incidence, and relative hazards from a prospective cohort....
