The location of her cancer isn't the typical location for HPV. What interest me is there have been several other people on here who were nonsmokers/nondrinkers and got cancer on their oral (upper) tongue in a spot that was irritated by a tooth or something else. I know supposedly that can't be a cause, but I wonder if in a small subgroup of oral cancers it is a cause and it just hides among the other causes in terms of being detectable.
