Vicky, I want to commend you for being such a strong advocate for your dad. The old "squeaky wheel gets the grease" thing has never been more true than with medical care.

I do know that "necrotic" essentially means "localized death of living tissue" and if that is the case, I am surprised that nothing has been done for six weeks. My non-professional opinion is that while part of the graft may be failing, this does not have to mean there is a recurrence of cancer.

As far as weight, another non-professional opinion is that the drugs and/or the radiation somehow messes with our metabolism. After my taste returned, I was able to eat like a linebacker for about a year before I started to gain weight.

Let us know what happens, and do keep getting in the faces of your dad's doctors until he is cared for properly.
