Intracholecystic Papillary Neoplasm with an Associated Invasive Carcinoma

No epidemiology observation is attached to this entity. Population statistics come from registries (SEER, CDC WONDER) and the IARC Global Cancer Observatory; IARC data stays under license review and SEER awaits credentials, so no burden figure is displayed. Statistics are attached per geography, year and sex — never invented or extrapolated.
