My cancer was under my tongue, no one could give me an explanation of why.........not smoking or drinking, it just happened, be sure, if you use psychotropic drugs that you are aware of the side effects, we have seen, especially with wellbutrin and zyban, horrid side effects.........also, antianxiety meds can wreck havoc.....make sure you have a competent dr. and don`t take anyone`s advice, but your own............
