The 5-year lung cancer survival rate is 17.8 percent as of 2015, according to the American Lung Association. The survival rate at the 5-year mark is significantly greater when cancer is found in its beginning stages while it is still localized to the lung area. Still, only around 15 percent of the people diagnosed with lung cancer are diagnosed with localized cancer.
When cancer is diagnosed after it has spread to distant sites, the 5-year survival rate is dramatically decreased to just 4 percent. More than half of those diagnosed with lung cancer die within a year of diagnosis.
Survival rates are slightly better for regional lung cancer. At this stage, lung cancer has spread regionally to lymph nodes. Regional cancer has a 5-year survival rate of 27 percent.
An annual average of 130,659 people in the United States were diagnosed with smoking-related lung cancer in the years 2005 to 2010, and smoking is the cause of 80 percent of lung cancer deaths in women and 90 percent of lung cancer deaths in men, as stated by the American Lung Association. Women who smoke are 13 times more likely than non-smoking women to develop lung cancer, and men are up to 23 times more likely to develop it than their non-smoking peers.
