Possibility of throat cancer.

I am facing the following symptoms since 1year: 1. Constant Sore throat 2. Rashes at the back of the throat 3. Voice change 4. Extra mass at the back of throat on tonsils side both side 5. Post nasal drip and excess saliva and phelgm at the back of the throat 6. Bad breath 7. Sometimes difficulty swallowing 8. Stiffness in the neck 9. Headache I went to nearest ENT in Feb 2022 and she said you have anxiety but I don't agree with her at some point it can be but NOT 100% its anxiety. I am attaching the reports. Is it possible that it can be throat cancer? I am really worried now since I have lost 15 kgs of weight since december 2021 Are these tests enough to diagnose cancer or I should see an oncologist? Doctors near me are not proceeding further even after these attached report findings. No smoking, alcohol habit
