I initially had a CT scan, with contrast, for swollen lymph nodes, which showed suspicion about the same time I had a FNAB, which confirmed the cancerous lymph nodes, so a PET/CT scan was dine to help ascertain a primary in the head and neck, and that showed extensive cancer in BOT, tonsil, vallecula, three bilateral lymph nodes, but a pandendoscopy or triple scope, under anesthesia, confirmed T1 cancer only in the left tonsil, in addition too the two lymph nodes. No scan is 100% accurate or can prove cancer, only a biopsy can, even that is subject to errors.

A PET/CT should be considered for stage lll and lV oral and oropharyngeal cancer, according to NCCN Guidelines, but as said, they are guidelines, and doesn't consider other factors that may be involved.

I hope this helps.
