Inclusion criteria
Inclusion criteria: Women with a US-visible breast mass were recruited from the First Affiliated Hospital of Zhengzhou University. Eligible patients will be woman aged 19 years and older with a breast mass revealed with palpation, mammography, US, or magnetic resonance imaging who were referred for breast US. And lesions with pathological results categorized as BI-RADS category 3,4,5 at US evaluation.
Exclusion criteria
Exclusion criteria: Women with breast implants and those who were pregnant or lactating, who were receiving chemotherapy or radiation therapy for any cancer, who had a history of ipsilateral breast surgery, or who were unwilling or unable to provide informed consent were excluded. We also excluded skin lesions, lesions that had been biopsied previously, lesions that were pure calcifications with no mass. Only a single mass was included from each participant in this analysis, with preference to including malignant lesions: If there was more than one malignant lesion in a given participant, then one was selected at random. If there were no malignancies, but multiple benign or high-risk lesions in a given participant, then one benign or high-risk lesion was randomly selected. Specifically, benign and malignant lesions were each sorted in random order for each participant, and the first malignant lesion was chosen, or, if there were no malignancies, then the first benign lesion was selected.
