: The foreign-born population in the United States has reached a record high over the last three years. Significant disparities in cancer screening rates exist among this population, resulting in later-stage diagnoses and worse outcomes. This narrative review explores the sociodemographic factors, barriers, and interventions influencing cancer screening rates among foreign-born individuals in the U.S. : A comprehensive review of studies was conducted to assess colorectal, cervical, and breast cancer screening disparities among immigrants. Factors examined include length of residence, race and ethnicity, income, education, citizenship, insurance, usual source of care, language, medical literacy, and cultural barriers. Furthermore, the effectiveness of educational interventions, patient navigators, and at-home testing in addressing these screening disparities was evaluated. : Immigrants have lower screening rates for colorectal, cervical, and breast cancer compared to U.S.-born individuals, with the largest disparities observed in colorectal cancer. Factors influencing these gaps include shorter duration of residence, Asian ethnicity, and lower income and education levels. Lack of health insurance and of a usual source of care are currently the most significant barriers to screening. Interventions such as education, patient navigation, and at-home testing have shown moderate success in improving screening rates, though data on their effectiveness remain limited. : Addressing cancer screening disparities within the U.S. foreign-born population is essential, especially as the immigrant population continues to reach record numbers. Targeted interventions are needed to improve screening among immigrant groups with the lowest completion rates. Future research on these interventions should prioritize larger sample sizes, longitudinal studies, and the utility of new technologies such as artificial intelligence.
