Cigarette smoking causes about 85% to 90% of lung cancers. One of the best ways to prevent lung cancer is to quit smoking and minimize your exposure to second-hand smoke (second-hand smoke can raise the risk of lung cancer even if you don't smoke).
There are a few other things you can do to help reduce your risk of lung cancer:
- Minimize your exposure to air pollution, asbestos, radon, arsenic, tar, and soot. Consider having your home tested for radon.
- Minimize occupational exposure to certain chemical that are carcinogens such as beryllium, cadmium, chromium compounds, chemicals used in rubber manufacturing, diesel engine exhausts, and bitumen used in roofing.
- Avoid burning coal indoors for cooking and heating.
- Avoid burning wood and other fuels
- Avoid frying foods in oil at high temperature.
- Be physically active (the Canadian Physical Activity Guidelines recommend at least 150 minutes of moderate- to vigorous-intensity aerobic physical activity per week, in intervals of 10 minutes or more).
- Eat a diet rich in fruits and vegetables.
If you're concerned about your risk of lung cancer, speak to your doctor to learn more about lung cancer prevention and screening.
