What is the California Dialogue on Cancer?

The California Dialogue on Cancer (CDOC) is the cancer coalition established by California’s Comprehensive Cancer Control Program in 2002 that serves as the vehicle for comprehensive cancer control in California. CDOC is a coalition of individuals and organizations working together to reduce the burden of cancer in the state of California. CDOC is comprised of representatives from a variety of organizations, constituencies, and interest areas in cancer prevention and control. Representation of this diverse group includes state and local governments; private and nonprofit organizations; health, medical, and business communities, and academic institutions; researchers; cancer survivors; caregivers and advocates.  

CDOC was created specifically to develop and implement California’s Comprehensive Cancer Control Plan (the cancer plan). The cancer plan is a strategic plan to reduce the cancer burden in our state, and is designed to provide guidance to individuals and organizations spanning a wide range of health and social disciplines that can play a role in reducing the burden of cancer.  Through a coordinated and integrated approach, CDOC implements planned strategies outlined in the cancer plan to reduce cancer in our state.

CDOC is administered by the California Department of Public Health and funded by the Centers for Disease Control and Prevention (CDC).  


To reduce cancer suffering and mortality in California through risk reduction, early detection, better treatment, and enhanced survivorship.


CDOC is led by an Executive Committee that includes the CDOC Chair, Vice-Chair, Immediate Past Chair, Workgroup Chairs, Advisory Council members, and the Comprehensive Cancer Control Program Director and staff. Click below to view members of CDOC's Executive Committee. 

CDOC Workgroups and Liaisons

CDOC Workgroups have been established based on objectives and strategies identified in the cancer plan, coalition priorities, and other relevant issues in cancer control. Current workgroups include Colorectal Cancer, Treatment and Survivorship, and Cervical Cancer/HPV. Each year, the workgroups prioritize and conduct activities that address these issues. Currently, workgroups are working on developing content for the 2021-2025 cancer plan. CDOC Liaisons represent key partner organizations in California’s cancer control efforts. Liaisons serve to inform the CDOC membership on their respective topics. CDOC currently has liaisons for four topic areas, which include American Indian/Alaskan Native, California Colorectal Cancer Coalition, Nutrition, Tobacco, and Cancer Data Use.
