How can I prevent lung cancer?

There is no absolute way to prevent lung cancer. However, there are things that will lower your risk.

  • Do not smoke. If you do smoke, quit. Avoid breathing in smoke from people who do smoke.
  • Reduce your exposure to chemicals known to cause cancer, such as:
    • Arsenic
    • Asbestos
    • Beryllium
    • Cadmium
    • Substances containing nickel or chromium
    • Coal products
    • Air pollution, such as exhaust from diesel engines
    • Radon. Have your home tested for radon, a radioactive gas that has no color or odor.
  • Eat a healthy diet.
  • Exercise regularly.
