California Cancer Registry

The California Cancer Registry (CCR) is California’s statewide population-based cancer surveillance system. The CCR collects information on almost every cancer diagnosed in California.

The California Teachers Study collaborates with the CCR to receive up-to-date data on the cancer diagnoses of our participants, which allows us to examine the risk factors for different types of cancers among our cohort.

All public school employees, ranging from kindergarten through community college, must pay into CalSTRS; they receive retirement benefits through CalSTRS and are CalSTRS members for as long as their retirement contributions are at CalSTRS.
