sodium iodide symporters & other information

I am doing research right now and also asking questions to other Thyroid Cancer patients about the information on that report. I understand some of it but not all.

It was explained to me that the I-131 ablation (treatment) will continue to work for a number of months to kill off all thyroid tissue, whether cancerous or healthy. Another lady said that uptake in salivary glands is very normal.

I Just read this online regarding sodium Iodide Symporters "...Other tissues in humans contain sodium iodide symporters: the gastric mucosa, salivary glands, mammary glands, choroid plexus, ovaries, placenta, and skin (Smanik and others 1996~. Breast tis- sue, which contains iodine symporters, can therefore pump iodine into breast milk." http://books.nap.edu/books/030906175X/html/45.html

it's from a report or book titled "Exposure of the American People to Iodine-131 from Nevada Nuclear-Bomb Tests: Review of the National Cancer Institute Report and Public Health Implications" from the National Academies Press
