"Reading" a mammogram
The mammogram is first checked by the technologist
and then read by a diagnostic radiologist, a doctor who specializes in interpreting x-rays. The radiologist looks for unusual shadows, masses, distortions, special patterns of tissue density, and differences between the two breasts (see photo). The shape of a mass can be important, too. A growth that is benign (noncancerous) such as a cyst, looks smooth and round and has a clearly defined edge. Breast cancer, in contrast, often has an irregular outline with finger-like extensions.
Many mammograms show nontransparent white specks. These are calcium deposits known as calcifications.
