Histopathology is the field that uses thin tissue sections, fixed and stained, and examined under a microscope to diagnose disease. By evaluating tissue architecture, cellular details, and patterns such as inflammation, necrosis, or invasion, pathologists distinguish between conditions like cancers, inflammatory diseases, and degenerative processes. The typical workflow involves obtaining a biopsy, processing the tissue, cutting sections, and staining (often with hematoxylin and eosin) to reveal characteristic features. This emphasis on the organization of cells within their tissue context is what sets histopathology apart, whereas cytology analyzes individual cells, microbiology focuses on infectious agents, and immunology centers on immune-related tests—often used as a supplementary tool in tissue diagnosis.
