Lung cancer remains one of the most prevalent cancers globally and is the leading cause of cancer-related deaths. The primary risk factor for this disease is tobacco smoking, with current estimates indicating that smoking is linked to approximately 80% of lung cancer fatalities.
However, lung cancer is not exclusive to smokers. About 10-20% of lung cancers are diagnosed in non-smokers, often due to exposure to environmental risk factors such as radon, secondhand smoke, asbestos, diesel exhaust, and various chemicals. Women are statistically more likely to develop lung cancer under these conditions than men.
