The only good news is that Dr Julie Sharp, science information officer at Cancer Research UK, said: "There is conflicting evidence about the role of HPV, and this rare type of mouth cancer.

"As this was a small study, further research is needed to confirm these observations."

"We know that after age, the main causes of mouth cancer are smoking or chewing tobacco or betel nut, and drinking too much alcohol."

So there is hope yet, though I am waiting to hear that gambling causes cancer as well, thus elimating all my fun in life.
