In current practice, the observed reduction in deaths from breast cancer among women participating in mammography is 40-60% [2, 3]. When a 2D mammogram and tomosynthesis are performed together (in combination mode), the study results in about twice the radiation dose to the breast as from a 2D mammogram alone and the dose is greater in thicker breasts. This allows the acquisition of "zoomed in" images (2 times How should the patient's arm on the side being examined be positioned for the CC projection? Note that all mammograms are done with some breast compression, but a spot compression test uses a special plate or cone which lets you see a clearer image of a much smaller area.
