Although rooted in the correlation of anatomical and histological changes with clinically apparent disease (and hence the iconic images of autopsy and microscope), modern pathology studies the causes of disease (etiology) and their expression/evolution (pathogenesis) at the molecular level using the tools of molecular genetics and biochemistry as well as analysis at the cellular and organ system levels. Because the first symptoms and signs of disease are often those of the body’s response to injury, the pathologist uses this response to provide critical clues as to the etiological agent and the likely mode of pathogenesis.
