Lung Cancer Prevention

What are the chances that I will develop lung cancer?

The #1 cause of lung cancer is exposure to tobacco smoke. Your chances increase with the amount you smoke and the number of years you have smoked. The more you smoke or are exposed to smoke from others (second-hand smoke), the greater your chances of developing lung cancer. People who have never smoked may develop lung cancer, but their chance is much less than people who smoke or who used to smoke.

What can I do to decrease my risk of developing lung cancer?

The best way to lower your risk is to avoid tobacco smoke. It is never too late to stop smoking, but the sooner you stop, the better. Even if you can’t quit completely, cutting back on the number of cigarettes you smoke can help, but cutting down is not as good as quitting completely.

There are many ways to stop smoking including counseling, nicotine replacement and medications. It takes most people several tries before they quit for good. So don’t be discouraged. If at first you don’t succeed, keep trying!

Are there other ways to decrease my risk of getting lung cancer?

There are many things that may reduce your risk, but none have been proven. These include:

What about screening for lung cancer?

The most effective way to reduce the chance of getting lung cancer is to stop smoking. There is also considerable interest in diagnosing lung cancer at an early stage, before it causes symptoms and when it is most treatable. This is called screening.

Research has found that using CT (“cat”) scans, computerized imaging of the chest or lungs, for screening reduced the number of people who died from lung cancer. As a result, several organizations, including the American Thoracic Society and the United States Preventive Services Task Force now recommend that healthcare providers consider ordering a chest CT for lung cancer screening for adults with a history of cigarette smoking. Talk to your healthcare provider about the risks and benefits of screening for you. There are decision guides that can help you weigh the risks and benefits of having a CT for lung cancer screening. You can find one of these on AHRQ website listed under resources.
