Smokers are 25 Times More Likely to Develop Lung Cancer.


Thanks to tobacco, lung cancer is now the deadliest cancer among American men and women. Evidence suggests that changes to the composition and design of cigarettes may have drastically increased the risk of lung cancer among smokers in recent decades.

In 1959, women smokers were 2.7 times more likely than non-smokers to develop lung cancer. By 2010, female smokers were 25.7 times more likely to develop lung cancer than women who have never smoked. Male smokers aren’t much better off. Their risk of developing lung cancer is 25 times that of men who have never smoked. Click here to learn more about the risks of lung cancer (page 9).


In addition to lung cancer, smoking also causes liver cancer and colorectal cancer, the fourth most diagnosed cancer in the United States. Evidence suggests that smoking may be related to breast cancer, and smoking among cancer patients and survivors increases their risk of dying.
