Hi Christine,
I am newly diagnosed and have gone through almost exactly the same thing - thyroid is the most treatable so everything will be fine, to yours is a rare more aggressive type of thyroid cancer we have to do lots of tests. I was diagnosed on Thursday last week and yesterday told by the specialist it was more serious. I'd love to talk to you more about the surgery (I'm expecting a complete thyroidectomy and lymph node dissection of everything on the right hand side). If you are happy to talk and share your experiences so far I would love to talk more.
Best of luck with your treatment, and I hope the body scan results were good news.
