Marliz,

Can't remember for sure, but I believe that it's about 50%??? of patients that end up with thyroid problems from radiation. I believe there is info on the main site. Please do a search there. The messages board searches are very informative, but also include a lot of opinions, not just facts. And although all of us crae a lot, none of us are doctors.

It's a simple blood test that I passed (?) the first time about 2 months post radiation. I am about 20 months now and flunked the lat test, so I am on mediacation for my thyroid. If in doubt just ask your doctor to run the blood tests.

Take care,
Dinah
