Simple answer: it doesn’t. But it does reduce known risk factors, so healthy living lowers the probability of contracting certain kinds of cancer. Prevention is a fool’s dream. Eg, there are many non smokers who never worked in a mine, or handled asbestos, or endured a smokey environment who have gotten lung cancer.

I’ve been trying to find it, but I read that 30% of smokers get cancer. My family didn’t get lung cancer but did get emphysema. Won’t matter to me because I’ll get dementia first.
