I forgot to mention that I am in the UK where the methods of treatment seem to be different. My son has had chemo and rad. and is fed by tube and developed an abcess in the tonsil bed, this has burst and the excrutiating pain he had been feeling has subsided, He has had a biopsy on the abcess and the doctors are being very pessimistic and are talking of an operation to remove the rest of the tumout. As yet we do not know if the abcess has live cancer cells. We will know on the 13th February.
