About Data from the CCR

The California Cancer Registry (CCR) provides aggregated cancer data for statistical purposes. Cancer statistics for California as a whole, for regions of the State, and for individual counties are available on our Query System. Questions that cannot be answered by our Query System, may be answered by contacting staff at the CCR.

Individuals also have the right to access records containing their personal information maintained by CCR according to CA Health and Safety Code Section 103885 (g)(10) and the California Information Practices Act, Civil Code Sections 1798 – 1798.78. Maintaining the confidentiality of persons whose cancers are reported to CCR is mandated by law and is the highest priority in registry operations. No data are intended to be used to identify individuals with cancer

All of California participates in the Centers for Disease Control and Prevention’s (CDC) National Program of Cancer Registries (NPCR), and in the Surveillance, Epidemiology, and End Results (SEER) program of the National Cancer Institute. CCR data meets all NPCR and SEER standards for quality, timeliness and completeness.
