Racism, discrimination, medical mistrust, stigma, and lung cancer screening: a scoping review

OBJECTIVE: Lung cancer screening can reduce lung cancer-specific mortality, but it is widely underutilized, especially among minoritized populations that bear a disproportionate burden of lung cancer, such as Black Americans. Racism, discrimination, medical mistrust, and stigma contribute to lower uptake of preventive screenings in general, but the role these factors play in lung cancer screening is unclear. We therefore conducted a scoping review to synthesize the literature regarding how racism, discrimination, medical mistrust, and stigma relate to lung cancer screening. DESIGN: Informed by PRISMA-ScR guidelines, we searched five databases for relevant literature, and two trained researchers independently reviewed articles for relevance. We conducted a narrative, descriptive analysis of included articles. RESULTS: = 1 article reported on discrimination. Results from empirical studies suggest that medical mistrust, distrust, and stigma may be barriers to lung cancer screening, whereas trust in health care providers may facilitate screening. The articles reporting on racism were commentaries calling attention to the impact of racism on lung cancer screening in Black populations. CONCLUSIONS: Overall, novel interventions are needed to promote trust and reduce mistrust, distrust, and stigma in lung cancer screening initiatives. Dedicated efforts are especially needed to understand and address the roles that racism and discrimination may play in lung cancer screening.
