Can you tell me maybe a forum or support group that would be able to answer some ??? He had 70 radiation/8 chemo treatments that ended Aug 29. Have not had another PET scan but the Dr looked down his throat yesterday and said he saw "something". He is doing a biopsy in two weeks. Not healed enough to do PET scan and we do not want false positive from that. We are now 4 1/2 mos. out of treatments and would like to know if this is what many have had happen to them. Thanks for any help.
