Evening. My query is this: My mum bit her tongue a long time ago which formed into a lump on the side of her tongue. This has stayed the same for a number of years with no change in size or shape or texture. The lump is soft, she has no pain from it and has had no symptoms. Her dentist has recommended a biopsy which of course is now concerning us. As it has been there so long i do not think it can be anything serious. What are your comments please? From Miss K.
