Just a quick note to say hi!
You didn't post ranges for you're labs so hard to tell. What I read says to me that your endo was doing a work up for autoimmune thyroid disease. I can't comment on what your labs mean,
Cancer is really diagnosed by a pathologist looking at the cells with microscope, and your FNA result was not cancer. Everything else is just him describing what he saw, little of which means anything except to another pathologist.
I feel bad, because I think you're fearful, but I think you're more or less okay.
