The CDC-funded National Program of Cancer Registries (NPCR) is a population-based surveillance system of cancer registries established in 1992. NPCR supports the collection of high-quality data by central cancer registries through funding, technical assistance, and the development of software for collecting and processing data. Through NPCR, CDC supports central cancer registries in 46 states, the District of Columbia, Puerto Rico, the U.S. Pacific Island Jurisdictions, and the U.S. Virgin Islands.
