[Breast calcifications]

Calcifications are found in many women undergoing mammography. The majority of these calcifications are benign. Calcifications suggestive for malignancy prove to be cancer in about 30% of cases after biopsy. Study and personal experience should result in ready recognition of characteristically benign calcifications. Calcifications suggestive for malignancy should be biopsied and the ratio of malignant over benign biopsies should be as high as possible. The purpose of this paper is to present a practical approach to the evaluation of breast calcification, by means of a survey of the pattern of calcifications in breast pathology. We describe six types of typically benign calcifications and six criteria that entail an increased risk of malignancy.
