[Fine-needle aspiration in the diagnosis of breast lesions].

A series of 250 patients operated on for lesions of the breast with previous aspiration biopsy is presented. Cytological and histologic findings are correlated and diagnostic validity of the cytodiagnostic method is expressed in terms of sensitivity, which is 0,937 and specificity, which is 1,007. The comparison of the diagnostic validity with other diagnostic methods shows the greatest value for cytodiagnostic in this series. The utility of the introduction of cytodiagnostics in the mass screening projects for delection of breast cancer is indicated.
