Traditional staining methods, such as Hematoxylin and Eosin (H&E) staining, provide essential insights into tissue architecture and cellular morphology. However, advanced staining techniques like Immunohistochemistry (IHC) and Fluorescence In Situ Hybridization (FISH) have further improved diagnostic accuracy. IHC uses antibodies to detect specific antigens in tissues, aiding in the identification of particular types of cancer. FISH, on the other hand, uses fluorescent probes to detect and localize the presence or absence of specific DNA sequences, crucial for diagnosing genetic abnormalities.
