[Diagnosis and treatment of non-palpable breast lesions: from the biopsy to the microhistology results. Our experience].

: The aim of modern senology lies in the diagnosis and treatment of non-palpable breast lesions (NPBLs). Through the diffusion of regional mammography screening the lesions being observed are continuously smaller, thus calling for more and more accurate methodology. Our experience in this area is based on the use of certain methods for retrieval and removal of NPBLs, such as Kopan's sec. philo-guide, ultrasound and advanced breast biopsy instrumentation. In our opinion methods allowing total removal of lesions in order to obtain complete histopathological characterization and enabling adequate therapeutic programs are to be preferred. In reviewing case studies a noteworthy increase of initial carcinoma (DCIS or LCIS), from 19.5% to 57.1%, has been observed in the last three years due to the extensive use of the aforementioned methods.
