Lung Cancer in Non-Smokers

Feb 28, 2025

Think lung cancer only affects smokers? Think again. Around 10-20% of lung cancer cases occur in non-smokers, often due to air pollution, radon gas, secondhand smoke, and genetics. Dr. Kamran Ali, Principal Consultant – Thoracic Surgery at Max Smart Super Speciality Hospital, Saket, explains how these factors contribute to lung cancer, particularly adenocarcinoma, which develops in the outer lung. Symptoms like a persistent cough, unexplained weight loss, and chest pain shouldn’t be ignored—early detection can make all the difference.
