Cancer among Immigrants: Diverse Histories, Diverse Disparities, Diverse Opportunities to Promote Equity

Abstract

Abstract Immigrants–people who live in a country different from their country of birth–constitute approximately 250 million people globally. Migrants are diverse in their reasons for immigration, ranging from those who are forced to flee their home country for survival, to those seeking a better life. Migrants face diverse barriers in access to care. Therefore, it is critical in the context of cancer health to improve our understanding of the epidemiology of cancer amongst migrants to inform policy, screening, and management. In this issue of Cancer Epidemiology, Biomarkers & Prevention, Yu and colleagues evaluate patterns in the incidence of infection-associated cancers–cancers of the stomach, liver, and cervix–amongst migrants in Australia. They demonstrate that the incidence of infection-related cancers is heterogeneous amongst immigrant populations, underscoring the value of studies that disaggregate groups in ways that reflect the diversity amongst these groups. In this editorial, we contextualize the work of Yu and colleagues in the setting of studies exploring cancer health amongst migrants in various parts of the world. We call attention to disparities in risk factors, prevention, screening, and access to care. Finally, we call on the research and medical communities to work to elucidate their diverse stories, understand their diverse disparities, and act upon diverse opportunities to promote equity.
