"Jemal, however, cautions that it is not the case that a never-smoker has a greater chance of developing lung cancer today than never-smokers did in the past."
we talked about this when we first noticed this trend way back then. as jemal points out, nothing has changed. the same population is getting lung cancer. its just that at one time in this country, everybody but fundy christians smoked, and even they sneaked around. bottom line - smoking doesnt cause cancer. never did.
