Nonpalpable breast lesions are being detected with the advent of improved mammographic techniques. Although only 20-30 % of these lesions are malignant, definitive diagnosis has usually required a needle- localization breast biopsy during a 6 year period were reviewed to determine the effect of this procedure on the diagnosis and treatment of early breast cancer. Calcifications were the most common mammographic abnormality for biopsy. Of the 62(27%) patients diagnosed with malignancy, 38 (61%) had invasive carcinoma and 24 (39%) had noninvasive carcinoma. Breast conservation was the most common form (53%) of surgical treatment in this study. Metastatic disease involving the axillary Iymph nodes was found in 23% of our patients who underwent axillary dissection. We conclude that needle localized breast biopsy continues to be a reliable method of detecting early breast carcinoma. Given the minimal morbidity, this procedure sould be done in all patients with mammographically suspicious nonpalpable breast lesions.
