A retrospective study is described according to which 319 outpatients had been operated on for suspected carcinoma because of breast lesion, in the course of three years in this hospital. In 113 cases (35.4%) the lesion was palpable, in 206 cases (64.6%) it was not. In the non-palpable cases, mammography was indicated in 98 patients (47.6%) undergoing controls for mastopathy, in 41 patients (19.9%) undergoing a first mammography in the course of preventive check-ups, and in 33 patients (16.0%) undergoing a check-up after operative therapy of breast cancer. prior to operation, 84.0% (n = 173) of the non-palpable lesions were marked by mammography, 11.2% (n = 23) by sonography, and 4.8% (n = 10) by magnet resonance imaging (MRI). Intraoperative specimen mammography was made in every case marked by mammography. In 19.4% (n = 40) out of the 206 cases of marked though non-palpable focuses a tumour was found. 25% (n = 10) of all marked tumours were diagnosed and treated as in-situ stage tumours, 65% (n = 26) were diagnosed and treated as tumours in the pT1 stage. As regards the nodal stage, 85% (n = 34) of the tumours were diagnosed and treated as being pNO tumours, and 100% (n = 40) were found to be free from any distant metastases. Consequently, for improving prognosis and, at the same time, for reducing the rate of breast amputations as a means of curative therapy of breast cancer, regular screening in defined risk groups is necessary. Surgical treatment of patients with small and non-palpable findings should be reserved for departments with marking and quick-freezing facilities.
