Thank you both very much.

Mike did have a dental visit and trays made to help protect his teeth, that also happened before treatment started.

He did have a full blood workup as well but I'm not certain of thyroid and testosterone levels, I'll ask.

He's eating 100% by mouth one week into radiation and getting about 2,000 calories a day. I can see that it won't be long before we start using the tube. He's been on a weight gain mission and gained 18 pounds before treatment started. His sense of taste is already messed up.

I'll read through your words of caution again and add them to my daily checklist of things I'm doing and looking out of.

I really appreciate everything you've shared and value your advice.
