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,
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. - Reviewer: Igor Puzanov, MD -
