Hi there! Sorry you had to join us here. Your wifes experience sounds pretty similar to mine. I had only one nodual, that is the difference. However, my endo was "on the fence" on RAI for me too. He said the same thing as yours. Some would recomend it and some would not. So, he left it up tp me. After thinking about it for all of about a minute, I decided to do it. It makes it alot easier to monitor blood levels, which is very important to test for any reacurance. Also, as far as other cancers, your wife, like me, will probably have a pretty low dose, which does not increase the chances of getting other cancers. You have to have alot of RAI for that to happen. In the end, I am glad I did it. It is just a little reasurance for me that all the cancer is gone. After she does the original treatment, she will have a scan that will show any left over thyroid tissue, or any cancer that may have got left behind. Then she will have a tracer dose once and a while and have the scan again. It is really the best way to detect any reacurance. It is a hard decision, I know. Good luck with what ever you decide, Skylog
