When I was first diagnosed with GD 9 years ago, the endocrinologist wanted to give me RAI immediately. I almost ran out of the office after she explained all the precautions I would need to take. This time around in April, I discussed my concern regarding cancer from RAI with 7 physicians (2 primary care, 4 radiologists, and my endo) prior to choosing the therapy. Not one of them could tell me of any direct correlation of cancer with RAI, especially for thyroid disorders since the doses are typically smaller than those received for thyroid cancer treatment. I also did my own research and really couldn’t find anything either. Cancer can be due to so many different factors and possibly including RAI so it’s really a personal choice that everyone needs to make.
