Vitamin C is also good in the prevention of lung cancer. Some studies suggest that people who regularly take 140 mg or more of vitamin C have lower risk of developing lung cancer than those who only get 90 mg or less of vitamin C dosage.

Lifestyle change is also vital in the prevention of lung cancer. People who smoke should consider quitting the habit. When a person stops smoking, his lung cancer risk is lowered by almost half in 10 years.

Finally, the second most common cause of lung cancer is exposure to radon, a colorless gas found in the ground. Test your home for any presence of radon. You can either buy a do-it yourself kit to check for radon which is available in your home supply stores or you can hire a professional to do it for you.
