Sounds like you have literally done everything that you can about this. Now it's time to just let go of it and let your doctor do what they do. You can't change anything by worrying all night about it, and Googling about it won't help either as you already know. You know that tonsil cancer is very rare, and based on your other post today you do have reflux which has probably irritated it and maybe it has even gotten infected (you also mentioned sinus drainage IIRC which could cause post-nasal irritation as well). I know it's easier said than done, but letting go is probably the best thing to do right now. Try to relax, listen to some happy music, get a good night's sleep and know that whatever it is, you'll soon find out, and then you can make a plan once you have all the information you need. Until then there's nothing more you can do about it.
