mammography

The Columbia Encyclopedia, 6th ed.

mammography

mammography, diagnostic procedure that uses low-dose X rays to detect abnormalities in the breasts. Tomosynthesis, also known as 3D mammography, is form of mammography that combines X-ray images taken at multiple angles to produce a single three-dimensional image. The early diagnosis of breast cancer made possible by the routine use of mammography for screening women increases a woman's treatment alternatives and improves her chances of surviving the cancer. Mammograms can detect tumors too small to be noticed on physical examination. Although opinions vary, it is generally recommended that women have a baseline study done in their thirties and have regular mammograms done at given intervals thereafter.
