An improved technique for needle localized biopsies of the breast

A technique using basic geometric principles is described that allows accurate determination of the location of the nonpalpable lesion in relation to the localizing wire tip and the skin. This method allows the surgeon to make the skin incision directly over the lesion, thus avoiding the creation of tissue flaps and minimizing the amount of tissue removed. While this technique is most helpful for lesions that are remote from the wire tip or buried deep within the breast, these principles are important in all biopsies of the breast. As the number of mammograms performed continues to increase, so will the number of needle localized biopsies, and surgeons must be familiar with techniques to simplify and improve these procedures. Breast conserving treatment for early stage carcinoma of the breast is an accepted form of treatment, and meticulous attention to the technical details of the biopsy will allow it to serve as the definitive surgical procedure. Avoidance of a second operation on the breast is preferable for the patient and will help to reduce health care costs.
