Hi. This is regarding my dad who is 65 yrs old. He had a tumor in his thyroid gland & underwent total thyroidectomy on 30th Dec 2011. The tumor was submitted for biopsy & turned out to be malignant. He underwent I 131 treatment on 7th Feb & on 9th Feb after the scan it showed that the cancer has metatasized to his left pelvic bone? Which stage of cancer is he in? And, is it curable?
You have not mentioned the type of thyroid caner. Iodine 131 whole body scans are done for Well differentiated type of thyroid cancer. With metastasis to pelvic bone this is stage 4 disease. Well differentiated thyroid cancer subtypes are curable with radioactive iodine therapy even in stage 4.
