[Recent progress in the diagnosis of nonpalpable breast lesions]

Recent advances in the diagnosis of nonpalpable breast lesions are reviewed. Recently, the technique of stereotaxic fine-needle breast biopsy for nonpalpable, mammographically detected breast lesions is available, and the technique has been proposed as an alternative to surgical biopsy. New equipment of stereo-guided breast biopsy system (LORAD co, system), which is produced for the use of stereotaxic core biopsy, is introduced. We examined 103 nonpalpable, mammographic lesions by this system and 14 carcinomas, including 11 noninfiltrating ones, were discovered. This system has been evident as a cost-effective and reliable method of evaluating mammographic lesions.
