Abstract
Stereotactic mammotome biopsy (mammotome) allows distinction between benign and malignant breast lesions on the basis of tumor spread. With the spread of screening mammography,mammotome biopsy has become more common. Between November 2006 and December 2008, stereotactic mammotome biopsies were performed for 134 microcalcificated lesions revealed by mammography. This report describes comparative analysis of category classification on the basis of detection opportunity and pathological findings. The series we describe included 72 patients who underwent mammography for medical examinations, 16 who underwent mammography performed by the same clinician who had examined the patient previously, 12 who underwent follow-up for microcalcifications, 10 who underwent preoperative mammography, 4 who underwent postoperative follow-up mammography, and 18 others, giving a total of 132 cases. Category (C) classification included C-2: 36 cases (27%), C-3: 49 cases (37%), C-4: 44 cases (33%), and C-5: 3 cases (2%). Among the 72 patients who underwent medical examination mammography, 15 had C-2 lesions,and all of them were benign. The C-2 in the microcalcification made checked by the medical examination MMG was benignancy, and thought to avoid excessive inspection. On the other hand, because the diagnosis of breast disease is difficult, we think that the mammotome examination on an ambulatory basis is useful for definitive diagnosis.
