Breast cancer screening imaging options have progressed greatly over the years in sensitivity, specificity, and image quality. According to DynaMed Plus, in 2012 there were 522,000 deaths by breast cancer and 1,677,000 total cases of breast cancer documented (Dynamed, 2018). For years, traditional screening for breast cancer involved 2D digital mammography which obtains two views of each breast. With advances in technology, the use of 3D breast tomosynthesis has become an advantageous addition to routine breast cancer screening protocols at many health care facilities.

• My literature review of articles was found in PubMed, DynaMed Plus, Cochrane Library, and Clinical Key from the year 2011 and on. The benefits of 2D digital mammography alone, 3D breast tomosynthesis alone, and 2D digital mammography combined with 3D breast tomosynthesis are compared. This study also compares the differences in radiation dose of each imaging option. The research demonstrated that 2D digital mammography combined with 3D breast tomosynthesis offers the lowest recall rates, the highest sensitivity and specificity, and increases the effectiveness of breast cancer screening.
