Thank you all for taking the time to respond. I have taken a look at the links and will do some more reading. The doctor I saw for my second opinion was at UCSF (at the cancer center). I saw him before I'd had my MRI. He said my surgeon is good and that I didn't need to transfer my treatment to UCSF unless the MRI showed the tumor was bigger than expected or had spread to the neck. My needle biopsy is tomorrow, so I will have more information soon. I guess if it comes back positive, the decision will be made for me. Thanks again for all your words. It really is helpful to hear from people with experience.
