@Dogfood I know it's a bit of a random comment, but I love your forum name.
I'm sorry to hear you qualify to join this thread, but it is at least a place with lovely supportive people who understand.
Well done getting through the CT scan. I am claustrophobic and was utterly terrified of the MRI, but have now done them so often I lost count ages ago.
Regarding your question about what is next in your treatment, I can't answer that unfortunately. My diagnosis was locally advanced breast cancer. I know from breast cancer that there are a whole load of diseases under the umbrella term 'breast cancer' with very different treatments, so I imagine there could also be more than one thyroid cancer disease, which could mean different treatment to a different thyroid cancer type.
Do you have a phone number you can call to speak to your nurse / clinic / unit / hospital? Otherwise maybe your GP? I can completely understand you need to know what is up next.
@catmomof3 Brachytherapy sounds awful from what you described. I'm sorry you have to go through it. I didn't have that - the radiotherapy I had was easy in comparison. I suffered dreadfully on chemo though, so I completely get your fear of going in and having such horrible treatment. It doesn't matter if you cry; I cried plenty at our chemo unit over the one and a half years I was a regular. I even screamed out one day so loudly the whole room heard and probably the whole building.
You will manage to get through it, and I will be thinking of you tomorrow xxx Let us know how you get on.
