169 Cancer RADAR – mapping cancer risk among individuals with a migration background across Europe

Abstract OP 32: Health Status 1, B210 (FCSH), September 5, 2025, 09:00 - 10:00 Aim: The WHO Action Plan for Refugee and Migrant Health highlights the need for strengthened migration health governance and data-driven policymaking. However, the absence of systematically collected and comparable health data among migrants remains a critical barrier. Approximately 12% of the European population (87 million people) has a migration background, and the risk of cancer among migrants can differ significantly from both their country of birth and their host country. Cancer RADAR aims to address this knowledge gap by providing a Europe-wide quantification of infection-related and screening-detectable cancer risks, stratified by migration background. We present the feasibility of such systematic data collection. Methods: Cancer RADAR explores the feasibility and methodology of mapping infection-related (liver, stomach, and cervical) and screening-detectable (cervical, breast, colorectal, and lung) cancer risks among individuals with a migration background across Europe. In collaboration with pilot cancer registries, we co-created a protocol to systematically collect cancer data stratified by birth country, serving as a proxy for first-generation migration background. Results: Cancer data stratified by birth country is available from 44 cancer registries and through data linkage from 8 cancer registries representing 20 European countries. Barriers to data collection include time constraints, limited infrastructure, financial resources, and the need for ethical approvals in the case of data linkage. Facilitators include the opportunity to contribute to decreasing inequalities in cancer outcomes and increase the visibility of a registry. Data from pilot cancer registries confirm increased risks for infection-related cancers and a similar or decreased risks for colon and breast cancer among individuals with a migration background, compared to the host population. Conclusion: We present the feasibility of quantifying and monitoring cancer risks among migrants, with the goal to provide actionable evidence to inform data-driven policymaking aimed at reducing health disparities.
