Hate to hear this...I have personally seen what this type of cancer can do. I know that God will heal Karl and I am praying for comfort for the family.
I am praying for Karl. Super nice guy and as someone said, an original here on CFF. Hopefully this is confined to one kidney and they can save the other one. I sure hope so. My thoughts are with you Karl, but trust me, miracles happen every day.
I agree with Bprice with having a gluten test,having been diagnosed with celiac
5 yrs ago, a simple test might be worth having done.Their several web sites
concerning gluten sesitivity and celiac available.
