Coincidental? Not directed at a cancer problem? Go figure! Regarding the difference between alcohol content over or under 25%... it's still in the mouth where alcohol acts as a solvent. We already know that substances are quickly and easily absorbed anywhere in the mouth. What could this alcohol be doing in other parts of the body? Could it make other tissue more vulnerable to carcinogens? Many forms of alcohol are found in hundreds of products we use every day. Remeber, logic doesn't count - they need a study!
