Social Disparities in Lung Cancer Risk and Screening

Significant disparities exist in lung cancer incidence and screening. Geographic, racial, gender, and socioeconomic disparities affect lung cancer incidence. As the leading cause of lung cancer, smoking varies among different racioethnic groups, genders, and socioeconomic statuses. In addition, environmental pollutants, such as radon, industrial toxins, and air pollution, are significant risk factors for lung cancer development that is disproportionately seen in working-class communities, as well as underserved and disabled populations. Lung cancer incidence depends on diagnosis. Literature examining lung cancer incidence and screening disparities have its limitations, as most studies are methodologically limited and do not adjust for important risk factors.
