Histological diagnosis of tumorigenesis involves examining tissue samples under a microscope:
- Biopsy: A small tissue sample is taken and stained using techniques like Hematoxylin and Eosin (H&E) staining. - Immunohistochemistry (IHC): Uses antibodies to detect specific antigens in the tissue, helping to identify the type and origin of tumor cells. - Special Stains: Techniques like PAS stain or Masson's trichrome can highlight specific tissue components, aiding in the diagnosis.
