Please Pray for My Grandpa

I just spoke to my grandpa who told me his doctor called. He had performed a CT scan on Monday and wanted my grandpa to schedule an appointment because it's "abnormal and they need to talk."

He's lost 20-30 lbs. in the last few weeks because he's not hungry, and is now taking to sleeping a lot and forgetting stuff. All 3 of his siblings have died of cancer in the past 15 years (his only brother as early as August) so I know that's in his family.

The doctor wants him to make an immediate appointment with a gastro-endurologist (I think that's what they're called), so they can put a scope into his stomach and see what's going on.

My grandpa's name is Hoover Cox, and I know he's very worried it's cancer. Please pray for God's healing. Pray for a correct diagnosis, correct treatment, and skillful doctors to take care of him correctly, making no mistake that would make him worse not better.

Also, any advice is greatly appreciated. Thanks.
