This chapter aims to ensure that comprehensive and understandable cancer-related surveillance data is collected, disseminated, and used for evaluating cancer control, planning, and monitoring in California.
Cancer surveillance is conducted under the guidance of the California Cancer Registry. The critical data is based on the comprehensive collection, analysis, and reporting of the population’s cancer incidence and survival rates and informs efforts to prevent and control cancer through research, planning, and policy in the state.
But while the existing cancer surveillance has proven to be useful to evaluate cancer risk, improve early detection, and monitor the effectiveness of treatments, there is a growing need to improve surveillance data to identify underserved, marginalized communities and strengthen efforts in precision for tailored medical care.
Linking cancer registry data with other population databases supplements surveillance and research efforts in a cost-effective way.
More value is added by improving medical information and annotated data obtained from electronic health records (EHR), including demographic and clinical information that supports the identification and surveillance of cancer patterns in medically underserved populations.
