I'm scheduled for RAI on Friday, and I've read from the forum that you have to sign a waiver. Why? The Doctor has insisted it's safe so what will I be signing a waiver for? Has anyone that is a member of this forum that had the RAI treatment gotten cancer? Can I accidently kill my cat? When I had the scan the first time I threw up, even though they said I shouldn't have. I lost my job and I will only have insurance for 3 more months. I feel like I may not be able to treat this later so I'm doing it now. Please let me know if you all think this is the right thing.
