Detailed Description

Women who are scheduled to take tirzepatide for weight loss will be assessed before and after taking drug for change in risk biomarkers. These include mammography, DXA scan, blood draw, and random periareolar fine needle aspiration (RPFNA) for acquisition of benign breast tissue.
