Other potential biomarkers for differentiating breast cancers and benign breast lesions include protein biomarkers such as the combination of epithelial membrane antigen and cytokeratin-1 (EMA and CK1; AUC of 0.9010), and developmental endothelial locus-1 (Del-1; AUC of 0.9200) [21,22]. This evidence concerns the gene EDIL3 and breast cancer.
