Just bumping up my post.
Thanks
To me, and this is just me. If they are both saying that the remainer of the thyroid will completely be destroyed anyway, and can not be 100% sure that there is not any more cancer, (now just me here, I would get the 2nd surgery).
Some people can't deal with the prospect of cancer remotely being in their body.
I had a tumor removed when they could not tell me if it was cancer or not, having a biopsy was not an option due to location. When I spoke with the surgeon and he basically said, "look we do not know what it is, whose to say five yrs down the road the tumor is cancerous after all and it has spread". His recommendation was to have it removed. Not cancerous, just a weird tumor in a strange location. (Laparotomy).
Now I have a brother who has a tumor in his head, but refuses to get any thing done about it because he says he does not want to know.
It all depends on what you feel comfortable with, you have to live with the ideas that will go through your mind. It could be nothing, like mine, or not. We just never know.
You will make the right choice that makes you happy.
