In 2015 the analysis of 820 cases was carried out and revealed 114 cases of histologically confirmed mammary gland cancer and 28 cases of benign tumors. Mammography was performed according to standard methods using mammograph of "General Electric" company with the mammary gland compression in two basic views – frontal and lateral. Ultrasound mammary gland investigation was performed using device "BK Medical" company, Denmark by linear array probe with frequency 10 MHz. Sequential scanning of all mammary glands quadrants was carried out. Mammography can be used quite successfully in complete mammary gland examination both screening without complaints and with complaints on the induration in the gland structure or after initial clinical examination. Skin, nipple and areola, subcutaneous fat with the Cooper's ligaments and blood vessels, glandular tissue with lactiferous ducts, as well as the retromammary space were analyzed on mammograms. Pathological formations were divided into 3 groups. 1. Nodular formations were determined on mammograms, within the glandular triangle the shadow of irregular shape with serrulated contour and increased intensity was defined. Spicular bundles from formation to subareolar area and in surrounding tissues were noted in 95 cases, which amounted to (83%). Revealed bundles were regarded as the signs of perifocal edema and lymphostasis, representing the generalization process. In given cases the post-surgical treatment was followed by radiation therapy. Local focal shadow of round shape with partially preserved clear separation from surrounding tissues, interchanging with areas that have indefinite and blurred contours was observed in 7 cases. Histological studies stated these cases as malignization of fibroadenomas. 2. In 8 cases the edematous-infiltrative form of mammary gland cancer was observed. The expansion of glandular tissue, in comparison with the healthy side, skin thickening up to 2-3 mm, expressed by the heterogeneity of the structure due to the rough fibrous bundles without premammary space was noted on mammograms. Puncture biopsy revealed metastases in localization of the primary focus in the bronchi. 3. The third group was represented by benign formations −28 cases, which amounts to 24.5%. Fibroadenomas amounts to 19 cases. Radiographs indicated oval formation of high density, with smooth contours and clear delimitation from the adjacent tissues.
