I've been searching the web for information concerning the link between alcohol consumption and oral cancer, but I'm not finding much truly useful information. To explain, I'll use the following two statements from an oral cancer information website: "90% of patients with oral cancer use tobacco." "Approximately 75% to 80% of all patients with oral cancer frequently consume alcohol." First, what does "frequently" mean in this context? Does it refer to how often alcohol is consumed, or the quantity consumed? (Thye're related but not the same.) Second, and more importantly, I can't tell from these two statements whether the frequent drinkers are also regular smokers. (And they probably are; it's no secret that alcohol and cigarettes very often go hand in hand.) This is quite typical of the information I've been finding. Does anybody know of any alcohol-cancer reseach or other information that controls for smoking? There are people who drink anywhere from moderately to heavily but don't smoke at all. I believe these people would have a much lower oral cancer incidence rate than people who smoke. Does anybody know of any research to back this up? Thanks for your input.
