Risk Factors. 
The following are lifestyle risk factors, which a person can modify to reduce his or her risk of getting lung cancer:
- The use of tobacco products: An estimated 85 to 90 percent of all lung cancer cases are caused by tobacco use, according to the U.S. Department of Health and Human Services.
- Exposure to secondhand smoke: When a person breathes in secondhand smoke, it is like he or she is smoking.
- Other suspected lifestyle risk factors include a diet low in fruits and vegetables, a diet high in cholesterol, heavy alcohol use, and smoking marijuana.
The following are environmental and medically related causes of lung cancer:
- Occupational exposures: Asbestos, mustard gas, radioactive ores, metals (chromium, cadmium, and arsenic), certain organic chemicals, and paint
- Environmental exposures: Radon gas released from soil or building materials, asbestos (among smokers), air pollution, and high levels of arsenic in drinking water
- Radiation therapy to the chest (especially for people who smoke)
The following are nonmodifiable risk factors (these cannot be changed):
- Family history of lung cancer
- Personal history of tuberculosis
To protect against lung cancer, individuals should avoid tobacco and secondhand smoke, consume a diet rich in fruits and vegetables, engage in recommended levels of physical activity, and maintain a healthy weight.
In January 2013, lung cancer screening guidelines recommending that health care providers discuss screening options with patients who meet certain high-risk criteria for developing the disease were released. High-risk patients are defined as those who:
- Are ages 55–74 and in fairly good health
- Have a smoking history equivalent to a pack a day for 30 years or longer
- Currently smoke or have quit within the past 15 years
Talk to your health care provider about whether you should get screened for lung cancer. Learn more.
