Histologic specimen being placed on the stage of an optical microscope Human lung tissue stained with hematoxylin and eosin as seen under a microscope Histology , [ help 1 ] also known as microscopic anatomy or microanatomy , [ 1 ] is the branch of biology that studies the microscopic anatomy of biological tissues .
The histological slides are then interpreted diagnostically and the resulting pathology report describes the histological findings and the opinion of the pathologist. In the case of cancer, this represents the tissue diagnosis required for most treatment protocols.
The slide is then given to the pathologist, who examines the tissue under a microscope, looking for any abnormal findings. The pathologist then prepares a report that lists any abnormal or important findings from the biopsy. This report is sent to the surgeon who originally performed the biopsy on the patient.
