I had papillary thyroid cancer 13 years ago. I had a total thyroidectomy and go for a thyroglobulin test yearly. My numbers were in the decimals. Last year I went through surgery, chemo and radiation for breast cancer and my thyroglobulin was up to 4. The doctor said that it was not related to the breast cancer. This year the thyroglobulin is up to 9! My TSH level was too high, so the doctor increased my synthroid dose. Now I have to wait 8 weeks with the new dose before I can repeat the blood tests in case the TSH is affecting the thyroglobulin. I had a PET scan follow up for the breast cancer this week. It was clear. I'm thinking that I'm having a recurrence of the thyroid cancer, but it is still too small to show up on the PET scan. Any body have any experience with this?
