With so many here that have had a missed diagnosis, and with so many 4 year ENT's that have not dealt with OPSCC, (it's the realm of 6 year ENT's that become head and neck surgeons) I would recommend that you get another opinion at a CCC. That way one more issue with a potential diagnosis will be eliminated, the doctors there see these every day. You don't say in your profile exactly where you are. Give us a geographic area and let us help you find the best cancer center near you that you can self refer to, and see someone that looks at oropharyngeal cancers every day. They will likely repeat the tests. If you come out of there without a cancer diagnosis, I would feel more comfortable looking at other possibilities.
