Cancer surveillance research can only be conducted with consistent, quality cancer data. To that end, this CRGC web page is dedicated to providing cancer registrars with information, tools, references and resources to efficiently and optimally perform cancer casefinding, data abstraction, and data submission. All elements on this web page serve to assist registrars in providing high quality and complete cancer data. For specifics regarding California cancer reporting standards, please visit the California Cancer Registry.
