The clinical value of aspiration biopsy cytology (ABC) in the diagnosis of breast tumor was reported. This report reviewed the results of 533 ABCs during a period of 8 years from 1983. Sixtyfour cases out of 97 indicating Class III, IV and V by ABC were confirmed pathologically. Fortyseven cases were diagnosed breast cancer and other 17 cases including 9 benign mammary dysplasia, 4 fibroadenoma, one papilloma, one duct ectasia, one phyllodes tumor, and one lactating breast were reported no malignancy. The ratio of the patients with breast cancer in Stage I and Stage II without lymphnode metastasis indicated beyond 60 percent. The larger size in diameter of tumor had the tendency to be diagnosed malignancy. However, some tumors of which size were smaller than 2cm in diameter could be identified breast cancer using the method of ABC. As fluid specimens aspirated from 5 cystic lesions out of 17 benign cases showed features of atypical cells, we should be very careful to diagnose by ABCs only. Clinically, ABC is a very useful examination for screening breast cancer, however, these results suggested that careful consideration was needed regarding ABC as definitive diagnosis. Therefore further diagnostic studies such as open biopsy or intraoperative frozen section were recommended.
