[Biopsy of non-palpable tumors of the breast]

14 biopsies were performed in patients with non-palpable tumors of the breast with stereotaxic automated system (ABBI) and disposable "pistol-needle" ("Auto-Suture") whose needle-harpoon penetrates into pathologic focus under local anesthesia (four fold digital stereotaxic control guarantees the precision of biopsy). Non-palpable breast cancer in the tissue areas of 4, 7 and 11 mm in horizontal section was diagnosed in 3 patients. Biopsy was performed outpatiently, there were no complications. The procedure is like a diagnostic sectoral resection of the breast.
