Avoiding exposure to cancer-causing substances will decrease your risk of developing lung cancer. Suggestions include:

  • Don’t smoke. If you smoke, talk to your doctor about ways toquit. Your risk of lung cancer decreases markedly and by 15 years is equal to that of non-smokers.
  • Avoid places where people are smoking.
  • Test your home for radon gases and asbestos. If these substances are in your home, have them removed.
  • Use protective gear if you must work around asbestos or other occupational hazards.

Making changes in your diet may help reduce your risk of lung cancer. Changes that may help include:

  • Eating a diet rich in fruits and vegetables.
  • Eating less red meat and more poultry.

If you are a smoker, talk to your doctor about quitting. The benefits of quitting smoking are much greater than the benefits gained from dietary changes alone.
