The non-palpable, radiographically suspicious breast lesion: an analysis of 101 cases.

Analysis of 94 patients with 101 non-palpable, radiographically suspicious, breast lesions revealed 46 malignancies (46%). Comparison of the malignant lesions with 225 palpable carcinomas (221 patients) removed surgically during the same period, showed a higher incidence of carcinoma in situ. Contrary, lymph-node metastases and distant metastases were, at the time of operation, distinctly less than in the patients with non-palpable malignant lesions. A breast-conserving therapy was more often feasible in patients with nonpalpable malignant lesions.
