<s>[INST] I have recently undergone hemethyroidocomy. i had lumph in right side of my neck. After testing I have been diagnosed carcicona. Now my querry is whether it is necessary to get removed other side thyroid lobe to have radioiodine therapy.Kindly suggest.Thanks in advance Gayatri Pandey [/INST] Hi, Greetings from Chat Doctor. From your description I think you are suffering from papillary carcinoma thyroid. Since it is a malignancy it is better to do a total thyroidectomy If you are a young person and if the disease is confined to one lobe some surgeons believe hemithyroidectomy is enough .but I think total or completion thyroidectomy is always advisable with radio iodine ablation. Hope you will be all. Right </s>
