Smoking is known to be a significant risk factor of lung cancer, which is the leading cause of cancer-related mortality in the world. In the United State, non-small cell lung cancer represents 85% of all lung cancer cases.
Lung cancer was known as an occupational hazard of asbestos workers many years ago; that’s why asbestos has been banned for many years although they could exist in some very old buildings. Also, it was reported that smoking and asbestos together can synergistically increase the risk of lung cancer.
In addition, exposure of several chemicals has been reported to be linked to lung cancer in the United States. These chemicals include chromium, formaldehyde, and nickel.
