Presurgical localization of breast abnormalities: an overview and analysis of 202 cases

The purpose of this study was to analyze cases undergoing imaging guided localization prior to surgical excisional biopsy of abnormalities in the breast and to describe the methodology utilized to perform such presurgical localization procedures. Presurgical localization of non palpable breast abnormalities is a simple, safe and effective procedure; it is now used more selectively for this indication due to availability of minimally invasive percutaneous biopsy procedures that can be performed under ultrasound or stereotactic guidance.
