Gary, was a neck dissection part of your treatment? If not, I am confused about how the doctors make the determination about lymph node involvement. In my husbands case, a second lymph node was discovered by pathology after neck dissection to have cancer cells, but it was not evident by any other means...palpitating or CT or even PET scan. This is something I have been wondering about. Thanks in advance if you (or anyone else) shed any light.
