About Lung Cancer
Could you be at risk for lung cancer? If you've smoked heavily or have smoked for many years, the answer is "yes." Smoking puts you at risk even if you no longer smoke or do not have any symptoms. There's no doubt about it--cigarette smoking can cause lung cancer. In fact, cigarette smoking is the leading cause of lung cancer. Every year, approximately 200,000 people in the United States get lung cancer, and more than 159,000 people die from this disease. Lung cancer is the leading cause of cancer death for men and women.
Your risk of lung cancer depends on how many cigarettes and how long you've smoked. Quitting reduces the risk, but half of all lung cancers occur in former smokers. See the publication What You Need To Know About Lung Cancer for more information about this disease.
The impact that smoking has on lung cancer is significant. For more information about smoking cessation and other lung prevention issues, see Lung Cancer: Prevention, Genetics, Causes.
