I cant' be much help help with glossectomies. My initial PET/CT showed involvement with the BOT, Valleculla, but on direct biopsy they weren't, and hope the same that it's scar tissue, inflammation or something else minor. I go to Beth Israel, and Mt Sinai in Manhattan. Another member here goes to Memorial Sloan Kettering Cancer Center. There are three SPOHNC support groups, in Manhattan at the first two hospitals mentioned, and one at NYU that meet once a month if you are ever interested.
Good luck with the biopsy.
