Hi Adam, I'm sorry too that you have need of this fabulous site. Of course you are scared. We certainly were, actually I was terrified. Your team is correct though, tonsil/ Oropharyngeal cancer is a very curable disease.
Paul has given you great advice and a great link to help with further information.
I want to add by asking and advising you to get to a Comprhensive Cancer Center. A CCC. These centres treat many many with this same disease and have experience. A local cancer Center may only see a couple of tonsil cancers a year. Research has proven CCC's to have better outcomes for their patients. They have a whole team approach with your case discussed by a tumour board. This consists of surgeons , chemo docs, radiation docs , dentists, Speech therapists, dieticians and many more.
Read as much as you can, ask many questions. We will all help you.
Tammy
