The purpose of this study at the University of Southern California in Los Angeles, CA, is to gain a better understanding of the changes that may occur in the breast when women use oral contraceptives (birth control pills) that contain different levels of the hormones estrogen and progestin. The researchers wanted to enroll 85 women. The Call to Action for this study was sent to Army of Women members on February 1, 2012. The researchers were able to close enrollment on March 29, 2013, after the Army of Women provided them with 120 women who were interested in enrolling in the study.
