I am a 31 year old female. In October of 2009, my thyroid was removed due to papillary thyroid cancer. Lymph nodes were removed at the time as well, and the cancer was found to have spread to one of them. I was treated with RAI, scan after RAI came back saying that nothing was absorbed outside the neck. 11/2010 my thyroglobulin levels were up to 39.6. I had an MRI done and a spot was seen on it, so I had a second surgery 12/10. Following this surgery, my thyroglobulin levels dropped to 1.6 within about 6 weeks. 6/11 my thyroglobulin levels started to raise again, and were at 2.1, in August 2012, I had another dose of RAI, after which, my level dropped down again to 1.3. I recently had blood work done again, and my thyroglobulin levels have started to raise again. This time is was 2.5. Does this indicate reoccurance or that there is still some thyroid tissue growing somewhere? I have an appointment scheduled with my endocrinologist, but its not for a month and I dont want to make myself crazy over nothing if it really is nothing.
