Can y'all pray for my father-in-law?

He recently went in to the doc because he was experiencing some back pain. It was very similar to what he had experienced when he had kidney stones. The scans didn't find kidney stones but they did find a growth in his pancreas. They don't know whether it is cancerous or not...they won't know until they open him up to remove it. If it is a fluid filled growth then the odds are it is benign. If it is solid then we worry about cancer. Please pray for him. He is a wonderful man and none of us want to lose him.
