No link so I don't know what to make of this exactly. When evaluating risk, though, you have to be careful. I think there was a study a while ago that stated that if a man eats a bacon sandwich every day for lunch it increases the risk of prostate cancer by 20%, which sounds pretty big. But since only ~5% of men have prostate cancer, the risk only goes from 5% to 6%. Not a significant change. Especially if you're in your 40s or older - the question you should be asking is not "what are the odds this will kill me" but instead "how many years does this effectively cut off my life." If smoking will take 20 years to kill you and you're 60, then the answer is that it's probably not going to have a significant impact on lifespan. Same goes for eating bacon.
It's somewhat funny that most people live their lives in reverse when it comes to evaluating risk - they take risks in their youth, when they have more life to lose, and become more risk-adverse in old age when it doesn't matter as much. We should all drive slow and eat healthy until our 40s, then start drinking, smoking and eating everything in sight.
Anyways, that was a bit of a tangent. As far as I'm concerned, if bacon is as bad for me as smoking then I guess I might as well start smoking because I'm never giving up bacon. Yep, that logic checks out.
