Lung Cancer Prevention

Lung cancer is the leading cause of cancer death in both men and women in the United States. While cigarette smoking is the leading cause of lung cancer, thousands of nonsmokers also die from lung cancer each year.

Reduce Your Risk for Lung Cancer

If you’re a smoker, the best way to avoid lung cancer is to quit smoking. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer.
Other risk factors that may increase your chances for cancer include:

  • Secondhand smoke
  • Exposure to asbestos and cancer-causing chemicals such as uranium, beryllium, vinyl chloride, nickel chromates, coal products, mustard gas, chloromethyl ethers, gasoline and diesel exhaust
  • Family history of lung cancer
  • High levels of air pollution
  • High levels of arsenic in drinking water
  • Radiation therapy to the lungs
  • Radon gas

Common Symptoms of Lung Cancer

Early lung cancer may not cause any symptoms. Symptoms depend on the type of cancer you have, but may include:

  • A cough that doesn't go away and gets worse over time
  • Chest pain
  • Coughing up blood
  • Shortness of breath, wheezing or hoarseness
  • Repeated problems with pneumonia or bronchitis
  • Swelling of the neck and face
  • Loss of appetite or weight loss
  • Fatigue
