A new study has linked air pollution to a rise in lung cancer among non-smokers, particularly affecting women and people in Southeast Asia.
Published in “The Lancet Respiratory Medicine” on World Cancer Day, the study reveals that lung cancer remains the most common form of the disease, with 2.5 million cases diagnosed in 2022. Researchers say adenocarcinoma, a key subtype, is now predominant among non-smokers, accounting for up to 70% of cases.
The highest levels were found in East Asia, especially China, where household fuel burning may be a factor. Scientists warn that as smoking rates decline, pollution-related lung cancer cases may continue to rise.
