Hi It has been three years since diagnosis of Nasopharyngeal cancer, stage 2B, and RO discovered small lump on the back of my husband's throat. Sent for Pet Scan and ENT visit. Both doctors said everything was fine. I got the Pet Scan report and it was advised that lump be watched and biopsied that it is probably from radiation but cannot exclude new tumor because of borderline results but there was no evidence of metastasised disease anywhere in the body. I am wondering why Drs said everything was fine. Will see Ent and RO in two weeks. Anyone have any thoughts.
