Can lung cancer be prevented?

Can lung cancer be prevented? Is it possible to prevent lung cancer under the protection of the question? The answer is the best way to prevent lung cancer is to avoid smoking and breathing in others. If you smoke, take smoke off. While the risk of former smokers is higher than non -smokers, the risk of infection still decreases with each year that runs to stop smoking. In fact, after ten years, former smokers reduce the risk of injuries by 30 % to 50 %. Simply, they did it! There is not much evidence that proper nutrition can occur, although there are many other benefits. Many attempts to reduce the risk of lung cancer have occurred in the past or present by smokers by delivering high doses of vitamins or medications similar to vitamins, but none of these experiments did not produce encouraging results. In one of the study, nutritional supplements associated with vitamin A, known as beta -carotene, increased the incidence of lung cancer, so the search should be started from the beginning.
