Changes in Breast Density and Breast Cancer Risk in Women With Breast Cancer and in Healthy Women

Urine samples will be assessed for levels of bisphenol-A

Patients and healthy participants complete a self-administered questionnaire providing detailed information on breast cancer risk factors, including demographics, behavioral and lifestyle factors, reproductive history, family history of breast cancer, comorbidities, medication and hormone replacement therapy use, and breast cancer screening history. This information is then cross-validated with documented data abstracted from medical records to provide a longitudinal and historical framework for assessing individual risk.

Mammographic density (MD) assessment: Patients and healthy participants are evaluated for patterns of longitudinal change in MD and subsequent breast cancer risk by retrospective review of screening mammograms performed prior to breast cancer diagnosis.
