Question about thyroid symptoms after head and neck radiation [View all]

My husband has done so good with his cancer treatments. ( base of tongue)
Now, he did have a small nodule on his thyroid before all treatment began, biopsy was inconclusive.
They didn't do anything because he was getting radiation and chemo of that area anyway.

So now it's two months after his last radiation and he has developed a goiter. We haven't seen the doctor yet, but I'm positive that is what it is. I also did a lot of reading and this is a side effect of radiation. I did message our main cancer doc this morning.

I guess what I am asking is if anyone has had experience with this?

OH!! and another weird after effect. My husband's facial hair has turned dark and thicker. It's only his upper lip and "soul patch" area. Weirdest thing because he has been rather baby-faced before. He has totally grey/white hair and was prematurely grey ( starting at age 35 or so)
