Lung cancer continues to be one of the most common cancers worldwide, claiming more lives yearly than breast, colon and prostate cancers combined.
Many people consider lung cancer a “smoker’s disease” as well as assume it is mostly a cancer found in men. However, while it is true that smoking is the top cause of lung cancer by a large margin, approximately 15 to 20% of cases in the U.S. happen in people who have never smoked or have smoked fewer than 100 cigarettes in their life. Being exposed to secondhand smoke can play a part, as nonsmokers have a 20 to 30% greater chance of developing lung cancer if they are exposed to secondhand smoke at home or work. Other factors may include radon, occupational exposures to carcinogens and outdoor air pollution.     Login or Subscribe to read the rest of this story.
