Lung cancer is the leading cause of cancer deaths in men in 93 countries and in women in 28 countries. And, it is the leading cause of cancer deaths in the U.S. among both men and women.


About 80 percent of lung cancer deaths in the U.S. are thought to result from smoking. The risk for lung cancer among smokers is many times higher than among non-smokers. The longer you smoke and the more packs a day you smoke, the greater your risk.


In 2018, approximately 30,000 Americans died of lung cancer, even though they had never smoked. In fact, if lung cancer in non-smokers had its own separate category, it would rank among the top 10 fatal cancers in the U.S.
