New Research Highlights Gaps in Lung Cancer Screening for Non-Smokers and Environmentally Exposed Individuals
Current lung cancer screening guidelines, primarily based on smoking history and age, are failing to identify a significant proportion of individuals who develop the disease. According to the International Lung Cancer Network (ILCN) and the World Conference on Lung Cancer (WCLC), a substantial number of lung cancer cases occur in people who have never smoked, those with lighter smoking histories, or individuals with prolonged quit times. The research emphasizes that occupational exposures (such as asbestos, silica, and diesel exhaust), air pollution, radon, prior lung disease, and family history are significant risk factors often overlooked by existing criteria. Women of Asian origin who have never smoked represent a growing demographic of lung cancer patients due to distinct biological and exposure profiles not adequately captured in current guidelines. Indigenous populations also face heightened risks from tobacco use, environmental exposures on traditional lands, and systemic disadvantages, yet they are...
