Hi, Thanks for writing in to us. It is important to review your condition in detail with imaging findings. A 1 mm and 2 mm mass in lymph nodes is less likely to be a cancer. These are too small to be told apart and can also be seen in many benign conditions. This requires clinical examination by a surgeon and correlation with your scan report. Since you had a total thyroidectomy in 2010, it will help to know the scan findings in the post operative thyroid bed and know if there is any suspicious malignant process going on. In the absence of a recent mass or lymph nodes of considerable size in the area it is difficult to call it a recurrent cancer. You should consult a head and neck oncologist and discuss your report and get examined. If required further testing will be asked like a FNAC or nuclear scan. Please do not worry.
