Breast cancer screening aims to detect the disease early on, when it may be easier to treat. Stephanie Patterson, MD, FACR, FSBI, Clinical Professor, Radiology, Division of Breast Imaging, University of Michigan, Michigan Medicine, speaks about the TMIST breast cancer screening trial, which will help determine if 3-D mammography is superior to 2-D mammography for breast cancer screening. The trial also includes the creation of a tissue bank for future research.
