I'm sorry to here of your recent concerns, but glad to hear you'll be going to Moffitt, which is one if the top centers in the country, and on the NCCN and NCI approved listings. Several members here were patients there, and if needed, do see Dr. Louis B Harrison who is the Radiation Oncology Chair, and senior member there, and leader in head and neck cancer.
Best wishes, and hopefully it's nothing major, but are doing right to be checked.
