Dan's blood tests came back showing hyperactive thyroid 20 months post treatment.

He had issues w/ not being able to gain weight, major fatigue, racing heart...and a host of other symptoms. Turns out it was toxic nodules that had grown on top of the healthy thyroid tissue. So, technically his thyroid was fine but the nodules were causing the symptoms.

After many months of debating about surgery or radioactive treatment...he finally got the radioactive treatment. This will kill the nodules and potentially some of the healthy thyroid tissues...which may mean he will end up on the synthetic thyroid.

Doctors aren't saying that radiation caused this...and, they aren't saying that it didn't.
