[Clinical diagnosis of breast cancer with nonpalpable tumor].
OBJECTIVE
To investigate the early diagnosis of breast cancer with nonpalpable tumor.


METHODS
Forty-six cases of clinical nonpalpable tumor were examined by mammography and sonography.The cases of nipple discharge were also examined by fiberoptic ductoscopy.


RESULTS
Breast cancer in 46 cases was diagnosed by pathological examination. Of them, 34 diagnosed with breast cancer were found with nodus, calcification or confused structure, and so on, 5 were considered benign tumor, and 7 were not found lesion by mammography. Thirty-one cases were diagnosed with breast cancer, 6 with benign tumor, and 9 were not found occupying lesion by sonography. Occupying lesions were found in 6 cases of nipple discharge by fiberoptic ductoscopy and were finally diagnosed by biopsy.


CONCLUSIONS
Mammography and sonography are important methods in early discovering breast cancer. Early diagnosis rate of breast cancer can be elevated by signs of early breast cancer and combined examination of mammograply and sonography.
