Whole Body Scan After Thyroid Cancer
Is thyroid cancer notorious for hiding anywhere in the body? Is that why I have to get follow up whole body iodine scans?
Thyroid cancer arises in the thyroid gland. It usually presents as a painless thyroid nodule. Most are papillary-follicular type and have a very good prognosis. Less common are medullary cancers, with an intermediate prognosis. Anaplastic cancers of the thyroid have a poor prognosis and are uncommon. Treatment of thyroid cancers involves removal ...Read more
2 weeks on low iodine diet for thyroid cancer whole body scan. Is vegan food ok during diet since it contains no dairy?
My endo want to do whole body scan with i-123 before having me go on rai for pap thyroid cancer. Shouldn't he do the rai first &whole body scan later?
Depends: It sounds like you are having rai now because you didn't do it initially, rather than having it to treat recurrent disease. It is reasonable to do the scan first to assess how much thyroid tissue is left in your neck, and whether there is evidence of disease elsewhere in your body. The dose of rai would then be adjusted by the findings. ...Read more
Can the i-123 whole body scan tell also if thyroid cells(cancerous & noncancerous) will uptake the i-131 during the rai treatment?(pap thyroid cancer)
Can a wbs after radioactive iodine identify other tumors elsewhere in body? What info is determined after this scan in those with thyroid cancer?
Common: Most people who have had thyroid cancer are "survivors", since it is very uncommon to die of thyroid cancer. Full body scans are typically done to see if there is any evidence for thyroid cancer elsewhere in the body. You need to be on a low iodine diet for 2 weeks beforehand, and typically it is done after receiving thyrogen for 2 days. ...Read more
If i had been cured from thyroid cancer..Radioiodine body scan negative. Do i still need suppressor dose of thyroxine?
I'll need radioactive iodine therapy in 2 weeks for my thyroid cancer.How can I get rid faster of the iodine in my body from a CT scan i had yesterday?
Not likely to work: If you received IV contrast with the ct scan, you will not be able to receive radioactive iodine in 2 weeks. It can take months for the iodine from the contrast to be excreted. You may be able to increase the rate slightly by taking a diuretic, but the best thing will be to wait at least 2 months. ...Read more
Same as plan iodine: You ingest iodine every day - in salt, salty foods, seafood, many breads, & red food coloring. The thyroid absorbs what it needs; the rest is excreted into the urine (+ a little into sweat, saliva, and other secretions). The i-131 atoms that decay in the thyroid cells (and give off beta and gamma energy that kills thyroid cells) become nonradioactive xenon-131 atoms, and are breathed out. ...Read moreSee 1 more doctor answer
3-4 weeks: Remnant ablation requires high levels of thyroid stimulating hormone (tsh), which will require one to be "hypothyroid". This means that synthroid needs to be stopped for approximately 3 weeks in order to achieve these elevated TSH values. For those that cannot tolerate being so hypothyroid, there is a recombinant human TSH that can be given, but this is very expensive and rarely covered expense. ...Read moreSee 2 more doctor answers
