Pathology is the scientific discipline that investigates the mechanisms, structural alterations, and functional consequences of disease in organisms, integrating molecular, cellular, tissue, and organ-level analyses. It encompasses the study of etiological factors, pathogenesis, and morphologic changes, as well as the correlation of these changes with clinical manifestations. Modern pathology spans subfields such as anatomical pathology, which examines tissues and cells, and clinical pathology, which analyzes bodily fluids and molecular markers, often using techniques like histochemistry, immunohistochemistry, flow cytometry, and genomics. As a core biomedical science, pathology provides the conceptual and empirical framework for understanding disease processes and informing diagnosis, prognosis, and therapeutic strategies.
Cells in our body are programmed to die after a certain period of time—a natural process known as apoptosis. This process is essential for maintaining the body's balance. When aged or damaged cells are not properly eliminated, ...
