Histology plays a pivotal role in the diagnosis of diseases. By examining tissue samples under a microscope, pathologists can identify abnormalities in the structure, composition, and organization of cells. This information is crucial for diagnosing conditions such as cancer, infections, and inflammatory diseases. Histological analysis often involves special staining techniques, such as Hematoxylin and Eosin (H&E) staining, which differentiate between different cellular components.
