Daisy, I had my submandibular gland removed, and I know a few other people here did too, but not the parotid. It must depend on where the cancer is to begin with.

I lost a bunch of weight during surgery and rad/chemo and the month or two after--almost as much as your husband--and I have gone from overheating easily to getting cold easily myself (except when I have hot flashes from the Tamoxifen I take!) and my thyroid appears to be OK, so just wanted to say I think that can change just due to weight loss.
