I have a similar situation. Surgery Nov 10, partial glossectomy, clean margins, no lymph node involvement but with perineural invasion. I am debating the radiation treatment, especially since it seems likely to come back. The whole situation is hard to comprehend and get used to in my life. I guess I had better. UCSF is a good place to be. A second opinion is always good. MY second ENT is the one who did the biopsy and diagnosis after I spent 5 months with an ENT who prescribed various drugs for the sore on my tongue and never did a biopsy. I wish the best for you. Thank you for sharing your experience.
