Is it gone?

Are you ok now?, is it gone? are questions I'm frequently asked when people learn of my dealings with thyroid cancer. I sure wish I had a definitive answer for them, but I don't have an answer for me yet either.
I had another set of bloodwork recently. The Tg (thyroglobulin) inched up a little from the initial 2.5 post op level to 4.2. How significant is that? Wish I could say, but apparently significant enough that my endocrinologist wants me to get another ultrasound in the next couple weeks instead of waiting to see me in March as scheduled.
I guess the answers to those questions will remain unanswered for now.

Merry Christmas and Happy New Year!
