<s>[INST] my niece had her thyroid removed due to having a tumor inside the thyroid gland, but thank God the tumor was benign. What worries me is that during the surgery the surgeon noticed some swollen ganglions and he tested them and they were cancerous. The doctor removed so many. My question is is there a posibility that she can develop more cancerous ganglions? And what is the prognosis for this situation. As far as I know he is gonna start her on a radiation pill within 3 weeks [/INST] Hi, dairy have gone through your question. I can understand your concern. She has thyroid removal but it is benign. Maybe she may have some lymph nodes which are positive for cancer. It can be due to occult papillary carcinoma of thyroid or some other malignancy spread to lymph nodes. Please send me histopathology report of that cancerous ganglion so that I know the type of cancer and I can help you further. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
