Breast calcifications: mammographic evaluation.

Breast calcifications may be categorized as benign, probably benign, and suggestive of malignancy. The interpretation scheme presented here utilizes a systematic structured approach: identify characteristically benign calcifications, for which no further evaluation is needed; define as suggestive of malignancy those remaining calcifications that present as isolated parenchymal clusters of tiny calcific particles; and (optional) attempt to downgrade some of these suspicious calcifications into the "probably benign" category, so that they can be managed by periodic mammographic follow-up rather than biopsy. The clinical acceptability of this approach will vary with local conditions; success in implementing it will encourage increased use of mammography, and ultimately, improved breast health care.
