Breast cancer is the most common type of cancer in American women. Chances of successful treatment are the greatest when the cancer is detected in its early stages. Mammography is a screening test which creates images of the breasts so a radiologist can locate suspicious areas. Mammography is not perfect, and researchers are working on ways to improve its accuracy. One type of technology to try make mammograms better is computer-aided mammography, also known as computer-aided detection (CAD).

In traditional mammography, a radiologist reviews an x-ray of the breast to locate any suspicious areas and determine whether further diagnostic testing is necessary. With CAD, the radiologist uses a computer program to help detect suspicious areas on a mammogram after the initial review is done.
