[Intervention studies in breast diseases].

Based on results of comprehensive examination of 20,000 females with different breast diseases in a specialized mammological room, the paper presents the most informative invasive techniques that combine diagnostic and therapeutical potentialities, such as ductography, cystography using various sclerosing solution, various types of needle biopsies under X-ray guidance, stereotactic computer devices, ultrasound study, and various labeling modes for nonpalpable formation before surgery. It shows in expedient to make a comprehensive examination under the conditions of a mammological room where the advantages of this or that invisable intervention, including those without a dosage load, are rationally, without duplicating, used depending on the diseases detected, which increases the significance of preoperative diagnosis up to 95-98%, including that of nonpalpable formations by substantially reducing the proportion of surgical interventions into the breast.
