What happened was that I sent my pet scan to my ENT doctor. His office called me and told me to take my pet scan to my oncologist (who treated me previously with radiation). When I got there, they made an appointment with the doctor for Sept. 12 The nurse looked at the hard copy of my PET scan and said that I would probably need a biopsy and could lead to chemo. However none of this has been confirmed. I don't think I'll have much more information until I see my doctor.
