How does mammography work?

Kenneth W. Chin (M.D., F.A.C.R.) gives expert video advice on: How should I prepare for a mammogram?; What does mammography equipment look like?; What can I expect when getting a mammogram? and more...

A mammogram works on the basis of allowing us to look at differences in density of the tissue in the breast. If there are areas that are particularly dense, especially in a certain pattern, then we become more suspicious that a cancer might be present. We also look for calcium deposits because some calcium deposits can be more suspicious or worrisome than others.
