Reducing Your Risk of Lung Cancer

Avoid Exposure to Cancer-Causing Substances

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 to quit. 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.

Eat a Healthful Diet

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.
The benefits of quitting smoking are much greater than the benefits gained from dietary changes alone.
