I had papillary
thyroid cancer in 2016 - total thyroidectomy followed by RAI. My cancer was restricted to the right lobe, no LNM, no invasion of tissues in the neck. At my last blood test, my thyroglobulin was 0.3 (down from 0.4) Is that a good number? Does it classify as undetectable? I always wonder if I'm low-risk of a recurrence?
