Risk Factors for Lung Cancer
|Secondhand smoking (also called passive smoking), which results from being in the environment of smokers, even if one is a non-smoker.|
|Being African-American because they are at a higher risk of developing lung cancer.|
|Asbestos exposure, which is associated with an increased risk of a type of lung cancer called mesothelioma.|
|Other industrial carcinogens (cancer causing substances).|
|Radon gas – an odorless gas that’s released into the air from the breakdown of uranium in the soil and water. It’s a good idea to have the home checked for radon, especially if one lives in an area where high radon levels often occur.|
