I am so sorry about your husbands cancer prognosis. My husband has cancer of unknown primary. He too had tonsillectomy and neck dissection. We had been in a fog of uncertainty for most of this year. We went to Rochester MN.Mayo Clinic for one month. Although they didn’t find the primary we have no regrets about going and seeking a second opinion. He had a TORS surgery there. We returned home for suggested treatment. He is now doing radiation and chemotherapy. I hope you find more support for yourself and your husband. My heart goes out to you as I know how hard it is not to know.
