Yes, non-smokers get lung cancer also while some smokers never get it, even heavy smokers. We all have cancer cells, it's just a matter of what triggers them into becoming active. Some are either lucky enough to never come across what might trigger it within them, or their immune systems cover it when they are triggered.
I've always wondered how some people can fall a distance that would kill a vast majority of people, but survive. I'm talking about skydivers who parachutes never open, yet they survive.
