Environmental Factors in Cancer: Focuson Air Pollution

Environmental factors, in the broad sense, are the primary causes of cancer in the United States, with most being attributable to modifiable risk factors such as tobacco use, exposure to sunlight and other radiation, and poor diet. A small, but non-negligible contribution to overall cancer risk is believed to come from environmental toxicants and a significant subset of which occurs as air pollutants. This later source of environmental cancer risk is the focus here.
