If you're a smoker your chances of getting lung cancer are pretty high.
But even if you don't smoke it's still possible to get lung cancer through carcinogens in the air or from second hand smoke from being around other people who smoke.
Not all smokers get lung cancer but they do usually get COPD which is a lung condition that makes it hard to breathe which can then cause you to need oxygen in later years.
If you've been smoking it's never too late to quit and you'll benefit your health as well as the health of others around you.
You'll even save thousands of dollars of money per year not smoking as smoking cigs are very expensive.
If you want to prevent your chances of developing lung cancer you should quit smoking now.
