This project will pool and harmonize existing interview data for 9,000 breast cancer cases and 7,855 controls who participated in four population-based studies. We will evaluate risk factors for breast cancer subtypes defined by ER, PR and HER2 status, including reproductive and hormonal factors and modifiable lifestyle factors, and assess racial/ethnic differences in risk factor profiles for ER+PR+ and ER-PR- breast cancers.
