I lost my brother in law to cancer of the pancreas and I understand your feelings and fears.
I also lost five brothers and my mother to various forms of this cruel disease. I am not a church goer and do not follow religeon strictly but I believe in God and pray daily and thank him for my wonderful family and ask that he protect them.
You have graciously asked for our prayers here and I add my prayer for your brother in law and hope you all find the strength to help you through this difficult time.

Kindest Regards,

Dave.
