Hi Donna, I hope you're okay I'm sorry to hear you're worried about these white patches on your tongue, I'd like to mention I am not a doctor and have no medical expertise in the slightest but as someone with their own anxiety of having cancer (a lump in my neck) I can relate to the anxiety that comes with seeing/feeling something that seems like it shouldn't be there. Please try not to panick just yet there are normally many other things it could be before the big C word and please keep us updated
