A planning committee will organize and host a 1.5-day public workshop that will consider the current state of knowledge regarding risk factors for cancer and strategies for interventions across multiple levels to reduce cancer risk. The workshop will feature invited presentations and panel discussions on topics that may include:

• An overview of the current evidence base for modifiable (e.g., environmental and behavioral) risk factors for cancer, including consideration of how these factors are distributed across populations and influenced by socioeconomic factors.

• Best practices and innovative approaches to implement population-based cancer prevention strategies, including the potential for collaborations with other disease prevention efforts.

• Opportunities to overcome challenges in the delivery of cancer prevention services within communities and health care settings, including consideration of specific strategies for low-resource areas.

• Opportunities to improve implementation of vaccine-based interventions for cancer prevention, as well as for pharmacological and surgical interventions to reduce cancer risk.

• Methods for assessing efficacy of programs and inventions for cancer prevention and risk reduction, including the identification and validation of biomarkers as surrogate endpoints.

The planning committee will develop the agenda for the workshop sessions, select and invite speakers and discussants, and moderate the discussions. A proceedings of the presentations and discussions at the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
