I do have appointments set up with ENT and MO in two weeks (4 weeks post treatment) and RO two weeks after that. I will definitely be bringing it up to get their take and for my piece of mind. I also just read a bit more on the NCCN site and it seems like they can do some tests in advance of the PET like a CT with contrast that helps to make an earlier decision whether to consider neck dissection.
All in all, sounds like I need to be armed with information and ask the questions at upcoming appointments. I remain concerned but hopeful and appreciate the info and personal experiences.
