The effect is much higher for lethal prostate cancer than the usual version almost any male would get if they lived long enough. I haven't seen what they consider the cutoff in any of the news briefs.<p>I had Gleason 3+3 prostate cancer, which is low on the lethality scale but if you have 4+4 or more the outlook isn't so good. And yes, I used to drink tons of coffee, maybe that bumped my Gleason score down, who knows.
