Yes, there is a biopsy. Doing a fine needle biopsy on a lymph node, if in fact it truly is in a lymph node, is not really very invasive. I said biopsy is invasive in my last post, but a fine needle biopsy is not invasive like a biopsy of a lesion on your tongue for instance. If they are doing an ultrasound, they should do a FNB if there is an enlarged lymph node where there is no reason for one.

There is no other definite test for OC. HPV is something they will determine later, from pathology. CT scan is usually done to catch things, but not again not definitive. So forget the ultrasound, MRI, oral tests. It would bother me that you have push for these things. You could always get an appointment at Moffitt for a second opinion, then determine later where to be treated IF necessary. (not shouting, just want you to realize there is still an "if" there) But, seems to me like your local medical personnel seem rather unconcerned. Can you politely inquire of them how many OC patients they treat?
