Abstract
Lung cancer is the number one cause of cancer deaths in the US population and in the global population. Approximately 85% of the lung cancers in men and 47% of the lung cancers in women are caused by tobacco smoking globally. Although tobacco smoking is, by far, the major risk factor for lung cancer, only about 10% of tobacco smokers develop lung cancer, indicating that other factors also play a role in the development of lung cancer in tobacco-exposed individuals. Among tobacco smokers, the development of chronic obstructive pulmonary disease (COPD) is by far the greatest risk factor for lung cancer. Although the majority of lung cancers are caused by tobacco smoking, a significant number of lung cancers develop in never smokers, representing 15% of lung cancers in men and 53% of lung cancers in women globally. These risk factors include family history/heritable factors, environmental tobacco smoke (secondhand smoke), exposure to certain cooking fumes (particularly among Chinese women), occupational and environmental exposures (radon, asbestos, arsenic, pollutants, etc.), hormonal factors, preexisting lung disease (including pneumonia and tuberculosis), dietary factors (including vitamin D levels), human immunodeficiency virus infection, human papilloma virus infection, and exposure to ionizing radiation.
