CAD After RT for Breast Cancer: The WECARE Study

Women <55 years of age at breast cancer diagnosis who were participants in the WECARE (Women’s Environmental and Radiation Epidemiology) Study were surveyed for coronary artery disease (CAD) outcomes following radiation therapy (RT). Participants were followed from the time of their breast cancer diagnosis until a CAD diagnosis or censoring event. Women who received left-sided RT were at more than twice the risk of a CAD event than women who received right-sided RT.
