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

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.
