NONPALPABLE BREAST MICROCALCIFICATIONS - FREQUENCY, MANAGEMENT, AND RESULTS OF INCISIONAL BIOPSY

In a series of 500 consecutive needle localizations, there were 165 biopsies for benign microcalcifications without a mass. An incisional biopsy was performed in 49 of these cases (30%). Follow-up mammograms were available for review in 39 of the cases. The average length of follow-up was 32 months. In no case did malignancy develop at the biopsy site. When an incisional biopsy is performed, careful follow-up mammography is an alternative to a repeated needle localization and biopsy in selected cases.
