Abstract

Abstract: The characteristics of early diagnosis of breast ultrasound in breast cancer were analyzed. The results showed that the diagnosis of breast mass was performed in 2548 cases of breast mass by convenient sampling method. The characteristics of misdiagnosis and missed diagnosis were analyzed in 132 cases of false negative (missed diagnosis) and false positive (misdiagnosis). The missed diagnosis and misdiagnosis of breast cancer by breast ultrasound were not related to the age of patients and the number of lesions (P>0.05). The independent risk factors of missed diagnosis and misdiagnosis in early screening of breast cancer were the maximum diameter of lesion, benign lesion, inflammatory lesion, edge of ultrasound image, microcalcification, axillary lymph node echo, obvious blood flow signal, complex and diverse lesion structure (P<0.05). Early screening of breast cancer using breast ultrasound diagnosis of missed diagnosis, misdiagnosis by a variety of factors, clinical diagnosis should pay special attention to reduce missed diagnosis, misdiagnosis rate.

Key words: breast cancer, early screening, breast ultrasound, missed diagnosis and misdiagnosis
