The incidence of lung cancer in never-smokers (LCINS) is increasing, with experts suggesting that climate change may be a driving factor. LCINS differs from smoking-related cancers, primarily affecting women and individuals of Asian ancestry as adenocarcinomas. During a plenary session at the 2024 World Congress on Lung Cancer, experts discussed the known and suspected causes of LCINS, including fallout from climate change, vaping, cannabis use, and airborne carcinogen exposures. Long-term exposure to wildfires has also been linked to an increased risk of cancer. Clinicians are urged to take action to improve healthcare outcomes and champion environmentally responsible efforts.
