The fact that some non-smokers get lung cancer in no way diminishes the fact that smoking greatly increases the risks of lung cancer.
Do you really believe that smokers are no more likely to get lung cancer than non-smokers?
I've been posting smoking threads on Free Republic since 2001. And I get just a little tired of the anti's that come in here and tell us that we are going to die horrible deaths, get lung cancer and die! I just wanted them to see it in writing that just because a person does not smoke is not a sure sign that they will never develop lung cancer. (Gawd, I hate that word).
If you followed the smoking threads you would see what I mean.
I certainly agree that:
1. not everyone who smokes will get lung cancer; and
2. some people who don't smoke will get lung cancer.
That said, I hope you'll agree that smoking does increase the likelihood of a person getting lung cancer.
