What causes lung cancer? The biggest cause of lung cancer is smoking, approximately 36,000 people in the U.K. die from lung cancer every year, 90% of those lung cancer deaths are from smoking. If you are a non-smoker there is a risk that you can get lung cancer from passive smoking, though the risk is not as high than if you smoke yourself.
