My DAD is 76 & has an ulcer on his tongue for the last 2 weeks, so GP sent him to hospital so we could find out whats going on, but the consultant had a look in his mouth & told us it's cancer & he needs a cat scan & a biopsy, plus he said my DAD has had it some because it is big (4cm)& it's under his teeth as well & i don't think my DAD hard him say it, we left without asking any questions as i think it's advanced as he's in alot of pain so not eating alot. So don't know whats going to happen?
