The diagnosis of neoplastic cells often involves a combination of clinical evaluation, imaging studies, and histological examination of tissue biopsies. Techniques used in histological evaluation include:
1. Hematoxylin and Eosin (H&E) Staining: The most common staining method used to evaluate the general morphology of tissues. 2. Immunohistochemistry (IHC): Uses antibodies to detect specific antigens in cells, aiding in the identification of tumor origin and type. 3. Molecular Pathology: Techniques such as PCR and FISH to detect genetic abnormalities associated with neoplasms.
