Welcome Teejay. Hopefully it is not cancerous, and PET scans do have false/ positives in the range of 10-14 percent, maybe higher in certain structures, including the tonsils, BOT which are rich in lymphatics. If it is cancerous, the BOT could have been the primary, which can progress to the tongue, but lesser the other way around or even metachcrounous or synchronous cancer due to carcinogen exposure. Just curious if you are a non smoker drinker, if not HPV related. They will probably do an triple scope, panendoscopy, while under anethesia before surgery to check your upper aerodigestive tract for any lesions. Surprised they did not do a FNAB, with sonogram guidance, for the suspicious lymph node to confirm cancer, but did hear of then doing the procedure such as yours, this way as not to disturb the lymph node as much, being surgery is likely. They usually like do do chemoradiation with 6 weeks following surgery, depending on your healing, or otherwise keep the "total treatment package" within 100 days for best results.

For me, surgery was the easiest, including the three neck dissections, followed by radiation, and chemo was the worst, due to my negative reaction, but everyone is different for a number of reasons.


Good luck with everything.
