[QUOTE=Reece;3303418]If you underwent radiation to treat the breast cancer, it could have definitely effected your thyroid function over time as well.

I would focus on getting to a place where you feel well.

I agree with Reece. A friend has leukemia and her treatment caused her to have hypothyroidism. She's on Synthroid now and doing fine. The radiation can cause your thyroid to not be at an optimal place.
