Experience of using the ABBI biopsy procedure in the diagnosis of non-palpable breast masses

Abstract

The Advanced Breast Biopsy Instrumentation procedure the improved biopsy csystem of the mammary gland was performed in 13 women aged 34 to 72 with nonpalpable mammographic lesions. It is a stereoscopic table making it possible to perform biopsy of the mammagraphic lesions of the mammary gland tissue by cannulas diameter up to 2 sm in under X-ray control. Microcalcinates are found in 3 patients (22,8%), the local tissue change in 3 patients (22,8%) focal shadows in 7 patients (53,2%).
 The lesion size 5 mm is found in 16% of the patients, from 5,1 to 10 mm in 25% of the patients, from 10,1 to 20 mm in 59% of the patients. The cancer was diagnosed in 3 cases (22,8%) on the 7 and 10 mm sites, the atypical hyperplasia in 2 cases (8,3%), other benign pathology in 53,2% of the cases. In all the cases the foci removal nas corfirmed by histology. The high efficiency of the biopsy stereotaxic method of the mammary gland which removes the roentgenosus-picious site as the single tissue preparation.
