Hi preaux,
The saying goes "It's not cancer until they say it's cancer".
The way to know for sure is to seek out and be seen by an ENT that has experience with H&N cancers. A biopsy of the suspicious node, lesion or area is the only way to know for sure. I can assure you that
Dr. Google knows nothing about this subject. While
HPV can be diagnosed in a woman, it's much more elusive in a male. It's detected when an actual cancerous tumor is biopsied.
Good Luck, positive thoughts and prayers
