Breast pathology

Where rare is common

Our breast pathology consultative service receives thousands of cases each year, spanning the spectrum of benign breast disease and diagnostically-challenging atypical lesions to conventional carcinomas and rare variants. We are fortunate to have expansive molecular and immunohistochemistry test menus to aid with diagnosis of rare breast tumors, and to have expertise in breast biomarker and companion diagnostic testing.
