Sorry for the graphic photo. Our 11 year old Lhasa apso had this growth found in her mouth (see pic) yesterday. Vet said it needed to come out and would send off for histology but refused to be drawn further on what it might be (benign or more malignant looking). I realise this is best as we don't know until we get biopsy back (she's having it out next Wednesday) but I can't stop catastrophising. It was an incidental find at a routine check. She had a tooth clearance eight months ago and it was not there then. She appears completely unaware of it still eats well etc., are there any vets that might be able to theorise? Anyone out there with a dog that had an oral cancer like this lump appears?
