The Greater Bay Area Cancer Registry (GBACR), in compliance with California state law, gathers information about all cancers diagnosed or treated in a nine-county area (Alameda, Contra Costa, Marin, Monterey, San Benito, San Francisco, San Mateo, Santa Clara and Santa Cruz).  This information is obtained from medical records provided by hospitals, doctors’ offices, and other related facilities.

The information, stored under secure conditions with strict regulations that protect confidentiality, helps the GBACR understand cancer occurrence and survival in the Greater Bay Area.  For each patient, the information includes basic demographic facts like age, gender, and race/ethnicity, as well as cancer type, extent of disease, treatment and survival. Combined over the diverse Bay Area population, this information gives the GBACR and all users an opportunity to learn how such characteristics may be related to cancer causes, mortality, care and prevention.

In addition to its local use, information collected by the GBACR becomes part of state and federal population-based registries whose mission is to monitor cancer occurrence at the state and national levels, respectively. Data from the GBACR have contributed to the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program since 1973. The nine counties are also part of the statewide California Cancer Registry (CCR), which conducts essential monitoring of cancer occurrence and survival in California.

GBACR data are of the highest quality, as recognized by national and international registry standard-setting organizations, including SEER, the National Program for Cancer Registries, and the North American Association for Central Cancer Registries (NAACCR). 

NAACCR Registry CertificationWe are pleased to display the GOLD seal from NAACCR, awarded to our registry for quality, completeness, and timeliness for 2012, 
which represents the latest evaluation period. 

Registry Organization and Funding Sources
The GBACR is organized into two components: (1) Registry Operations and (2) Cancer Surveillance. Registry Operations is responsible for receiving, quality-controlling, and submitting the data to our funding agencies, while Surveillance is responsible for conducting and facilitating research using cancer registry data to examine patterns of cancer incidence and survival in the Greater Bay Area and throughout California. In addition, the many research studies conducted using GBACR data are funded primarily by federal and state cancer research programs. 

The GBACR receives its funding from the National Cancer Institute, the California Department of Health Services and the Centers for Disease Control and Prevention.
