Ultrasound-based Diagnostic Model for Differentiating Malignant Breast Lesion From Benign Lesion

Ultrasound-based Diagnostic Model for Differentiating Malignant Breast Lesion From Benign Lesion

This study proposed to construct an ultrasound-based diagnostic model for Differentiating Malignant Breast Lesion From Benign Lesion. This study contains both retrospective and prospective part, which are designed for model construction and independent validation, respectively.This study aims to construct an easy-to-use ultrasound-based model, prove the efficacy of the model for identifying malignant breast lesion from benign lesion, and finally promote the application of this diagnostic model in more clinics.

Inclusion Criteria:

• female
• with single breast lesion(maximum diameter>0.8 cm)
• agree to receive follow-up in six months and take the second breast ultrasound six month after the first breast ultrasound, if a benign diagnosis is achieved at the first ultrasound
• sign the informed consent

Exclusion Criteria:

• lost to follow-up
• failed to take the second breast ultrasound six month after the first breast ultrasound
