Accessing CCR Data

The main goal of cancer registries is to collect and aggregate data, which is then analyzed by researchers. Analysis by researchers increases our knowledge of various cancers, which improves cancer diagnosis and treatment practices over time.

CCR is required by law to share the aggregated data that it collects. CCR provides statistics, reports, and tools that are intended for use by researchers, patients, and the general public. This includes cancer statistics for California as a whole, statistics for specific regions of California, and statistics for individual counties.

Cancer patients also have the right to access their own personal data files from CCR. Reporting of cancer cases is required by law and so, too, is the protection of the privacy and confidentiality of this sensitive data. No data may be used to identify individuals with cancer. Maintaining this confidentiality is one of our highest priorities.

This section of the site includes the following resources, many of which may be found in our Data Library:

  • Cancer fact sheets
  • Special reports on cancer in California
  • Information for researchers who are interested in requesting data from CCR
  • Information for patients or others with legal authorization who are interested in requesting an individual’s CCR case file
  • The CCR Interactive Query Tool, which provides cancer information by region
  • A compiled list of publications in scientific journals that includes CCR data
  • Data and statistics on geographical variations in cancer, generated using our Geographical Information System (GIS)
