[Radiographic characteristics of nodular cancers of the breast with delimited forms of growth].

The results of examination of 1,080 patients operated for carcinoma tuberosum of the breast at the clinic of the Institute in 1968-1978 are discussed. Distinct boundary of tumor growth was established in 281 cases by gross examination of tissue obtained by mastectomy. The results of X-ray examination were improved by means of histotopographic sections of tissue specimens in 100 cases. It was shown that distinct boundary of the growth of carcinoma tuberosum of the breast may be adequately identified in most cases on the basis of mammographic evidence (even, undulate or polycyclic contour of malignancy). Also, it was established that mammography offers a more adequate means of preoperative identification of the actual size of tumor than palpation does. An analysis of the mammographic picture contributes to the choice of the most efficient scheme of treatment of breast cancer patients.
