Hi,
I am sorry about your Dad being hospitalized.

You know, I wonder if chemo causes that because my husband has had to be hydrated three times already this month. Just tonight I checked his skin and it is sticking...NOT good. I try to get him to drink water/pop/juice...but the man does not have any desire for beverages, he never really did - so I stress the importance this to him...but he won't do it.

I wonder if the chemo takes away thirst? Hmmm
Okay, I was wondering about the staging...if they revert back, etc., so thank you for explaining that.
Let us know how your Dad is doing, and hang in there...this is not easy, I know.
Mary
