Abstract
OBJECTIVES: To review recent developments in cancer disparities affecting displaced and migrant populations in the U.S.-Mexico border region and identify barriers in public health and epidemiologic tracking. METHODS: A structured scoping review was conducted using peer-reviewed studies and public health data published between 2010 and 2024. Sources included PubMed and governmental and binational public health reports. Inclusion criteria focused on border-specific, cancer-related evidence involving migrant and structurally vulnerable populations. RESULTS: Cancer inequities were commonly associated with limited screening access, underinsurance, fragmented care, and binational surveillance gaps. Environmental and occupational exposures were identified as potential risk factors in border communities. Language barriers and mistrust of health systems limited engagement in preventive services, treatment continuity, and research participation. CONCLUSION: Cancer inequities among migrant populations in the U.S.-Mexico border region are closely linked to structural and policy barriers and gaps in cross-border epidemiologic infrastructure. Improved binational surveillance, culturally responsive outreach, and expanded access to screening and timely care may support more equitable cancer control.
