The Cancer Prevention at Work (CPW) project researches the cost-effectiveness and social acceptance of incorporating prevention of cancers associated with Helicobacter pylori, Hepatitis C virus and Human Papillomavirus into ongoing primary occupational health surveillance programmes. The project involves workers and their families, policymakers, occupational health organizations, health authorities, companies and workers’ representatives, and cancer and patient organisations, among others, to identify the best strategies to increase the adherence of the population of workers in screening programs of infection-related cancers.
