Rationale:

The main purpose of this study is to find out if screening for breast cancer with tomosynthesis mammography (3D) is better than with digital mammography (2D). The study will compare the two technologies and their ability to reduce advanced breast cancer in the screened population. This study will also compare the number of other/additional tests recommended after each mammogram.
