Crossing Borders, Missing Data - Cancer Inequities in Displaced and Migrant Populations: A Scoping Review

Area of Science:

• Public Health
• Epidemiology
• Cancer Research

Background:

• Cancer disparities disproportionately affect vulnerable populations.
• The U.S.-Mexico border region presents unique challenges for public health.
• Migrant and displaced populations face specific barriers to healthcare access.

Purpose of the Study:

• To review recent developments in cancer disparities affecting displaced and migrant populations in the U.S.-Mexico border region.
• To identify barriers in public health and epidemiologic tracking for these populations.

Main Methods:

• A structured scoping review of peer-reviewed studies and public health data (2010-2024).
• Searches included PubMed and governmental/binational public health reports.
• Inclusion criteria focused on border-specific, cancer-related evidence involving migrant and structurally vulnerable populations.

Main Results:

• Cancer inequities linked to limited screening, underinsurance, fragmented care, and surveillance gaps.
• Environmental/occupational exposures identified as potential risk factors.
• Language barriers and mistrust hindered engagement in preventive services, treatment, and research.

Conclusions:

• Cancer inequities in this region are tied to structural/policy barriers and cross-border epidemiologic gaps.
• Improved binational surveillance and culturally responsive outreach are crucial.
• Expanded access to screening and timely care can promote equitable cancer control.
