The proportion of lung cancer cases in people who've never smoked is increasing, with air pollution being identified as a significant factor. Adenocarcinoma is a dominant subtype of lung cancer among never-smokers and is linked to air pollution, particularly in east Asia. Lung cancer remains a leading cause of cancer deaths globally, with adenocarcinoma becoming the most common subtype. Symptoms of lung cancer are often not obvious in the early stages, making it challenging to diagnose.
