Social Determinants of the Lung Cancer Care Continuum

Lung cancer is the leading cause of cancer death (1). Unfortunately, lung cancer affects certain populations disproportionately in terms of risk, screening, detection, and treatment. For example, smoking increases the risk of getting lung cancer by 10 times, and those in lower income brackets and of lower education level are 2 to 3 times more likely to be smokers (2,3). Though annual lung cancer screening can decrease mortality (4), minority and underserved populations are less likely to participate in screening and less likely to follow-up after a baseline scan (5-7). Low participation and compliance with lung cancer screening creates a missed opportunity to reduce mortality among these populations, thus exacerbating lung cancer disparity (7). Even when diagnosed, African Americans and those in the lowest socioeconomic quartile have significantly lower survival from lung cancer compared to others (8,9). This work details how disparities along the continuum of lung cancer care result in higher and morbidity.
