VIN3 = appearance of: cells under microscope, judged to be most abnormal, "pre-cancerous appearing" yet not clearly cancerous; see: https://www.google.com/#q=VIN3. Cancer in situ simply means no other sites (metastasis) of similar cells have been identified/recognized to be present. The 2 key definitions of cancer are: (1) Invading adjacent normal cells &/or (2) also growing in other parts of body (metastasis).
