Lung cancer is the leading cause of cancer death in the United States in both men and women.
Like other cancers, lung cancer occurs after repeated insults to the genetic material of the cell. The incidence of lung cancer in other countries follows their smoking patterns. Some other carcinogens known to cause lung cancer are found in the workplace. These include bischloromethyl ether and chloromethyl ether in chemical workers, arsenic in copper smelting, and asbestos in shipbuilders and other asbestos workers. Radon poses a risk to uranium and fluorspar miners and may pose a risk in some private residences as well.
