Pathophysiology of oropharyngeal squamous cell carcinoma?

There isn't room here for a discourse in identification and treatment of head and neck cancer. But to telieve yoiur concern please go and get checked. Caught in the first six months these conditions have a high (80%) healing rate. The stats are reversed for late diagnosis.

That is subject for a textbook chapter, but in short tobacco and alcohol consumption, HPV infection, immunosuppression among others are well recognized risk factors. Treated early, good chance for cure.

Abstain from alcohol, and tobacco, get HPV vaccine. For info: https://my.clevelandclinic.org/health/diseases/12180-oropharyngeal-cancer#:~:text=Oropharyngeal%20cancer%20is%20a%20type,lining%20your%20mouth%20and%20throat.
