What a Radiologist Needs to Know about Breast Pathology Processes

Optimal breast care requires a multidisciplinary and integrated approach, including appropriate processes and communication between the radiology and pathology departments. It is important for breast radiologists to have an understanding of the important events that occur between the time a percutaneous biopsy sample is obtained and the point at which the final pathology report is issued. This article reviews the essential processes from breast biopsy through to pathology diagnosis, including the general pathology workflow, tissue preparation, immunohistochemical staining, and pathologic reporting. Upon completion of this educational article, participants will have gained an understanding of the essential steps in the pathology workflow. This article will also highlight the important clinical information a radiologist should provide to the pathologist to ensure the most accurate and clinically relevant diagnosis. This clinical information includes the BI-RADS assessment category, the type of imaging finding that was targeted for biopsy (particularly when there are calcifications), the location of the targeted lesion relative to other findings, and other pertinent patient history.
