We attempted to appraise the ability of ultrasound and subsequent fine-needle aspiration biopsy and cytologic examination in the screening of breast cancer. To find nonpalpable breast cancers, we performed whole-breast scanning on those patients with breast disease who visited the outpatient clinic of this institution. Three hundred and three nonpalpable solid breast lesions were detected by ultrasound in 2227 whole-breast examinations. One hundred and five of these 303 lesions were subjected to ultrasound-guided fine-needle aspiration biopsy and cytologic examination (USGABC). Cytologic findings indicated that the lesions were definitely malignant in 9 cases; suspicious in 7 cases, which included two confirmed cancers; and benign in 74 cases, which contained no cases of false negative. Surgery confirmed malignancy in 11 (0.49%) of the 2227 cases in which whole-breast scanning had been performed. Whole-breast scanning and subsequent USGABC are useful for detecting nonpalpable breast cancers and determining choice of surgical treatment procedure.
