The Rhode Island Cancer Registry (RICR) has collected cancer case reports since October 1986. Since 1995, this effort has been supported in part by the National Program of Cancer Registries (NPCR) of the Centers for Disease Control and Prevention (CDC), a federally mandated program that supports population-based cancer surveillance systems. RICR collects and processes high quality and standardized newly diagnosed cancer data on the type and extent, as well as patient demographics and selective cancer treatment information. RICR produces comprehensive epidemiological reports on cancer – incidence, prevalence, and mortality – by different attributes. Healthcare providers’ reporting of cancer cases is mandated under the Rhode Island General Law 23-12-4.
