Smoking is the biggest cause of lung cancer – but it's not the only one. According to the Environmental Protection Agency, exposure to radon is the second leading risk factor for lung cancer and the No. 1 cause of lung cancer among non-smokers. The World Health Organization says radon causes up to 14 percent of lung cancer deaths worldwide, and in the U.S., about 21,000 lung cancer deaths per year are due to radon. Of those, about 2,900 occur in people who never smoked.
