Areas under the receiver operating characteristic curves (AUCs) of the model with the internal test set (a), the external test sets (b), the external test set A (c), and the external test set B (d). The confusion matrices of the model in distinguishing benign and malignant breast lesions with the internal test set (e), the external test sets (f), the external test set A (g), and the external test set B (h). Actual class, the pathology diagnosis; Predicted class, the binary prediction result of the deep learning model
