Hello, I’m 27 and I was diagnosed with papillary thyroid cancer. I underwent total thyroidectomy and RAI treatment last year. 6 months post my surgery my thyroglobulin levels are <0.20 ng/dL but ultrasound showed enlarged level 2 lymph nodes but all are discrete and has fatty hilum , I’m currently taking 175mcg Thyroid medicine and my latest TSH was <0.01 mu/L, but T4 is raised to 22.9 pmol/ L. Can this be a sign of anything wrong? Should I be worried?? Please can you let me know.
