Reminds me of when I ask my Papa if he was going to get cancer from smoking, he told me it was all a lie to get people to stop smoking and there was nothing wrong with it...
I wouldn't go that far, but the risks are indeed vastly overstated. For "smoking causes cancer" to be true, every smoker would have to develop cancer yet less than 40% of lung cancer patients smoked.
The real risk factors for cancer are many. From flame retardant chemicals in most products in our homes, to the very air we breathe. What contributing factor finally starts cancer cell replication can't be determined. Best we can is minimize risk factors. But who gets cancer who who doesn't is more about our genes than risk factors. Many centarians smoke, drink, eat crap and outlive health gurus. It's genetic, not causal.
