RISK FACTORS
Many cancers are related to specific environmental and lifestyle factors that predispose a person to develop cancer. Accumulating data suggest that some of these risk factors initiate carcinogenesis, other risk factors act as promoters, and some risk factors both initiate and promote the disease process.

Air pollution
Air pollution has been linked to the development of cancer, particularly lung cancer. Persons living near industries that release toxic chemicals have a documented increased risk of cancer. Many outdoor air pollutants ¡ª such as arsenic, benzene, hydrocarbons, polyvinyl chlorides, and other industrial emissions as well as vehicle exhaust ¡ª have been studied for their carcinogenic properties.

Indoor air pollution, such as from cigarette smoke and radon, also poses an increased risk of cancer. In fact, indoor air pollution is considered to be more carcinogenic than outdoor air pollution.
