God bless you and grant you the strength to remain positive. My cousin is going through the same thing with stage 4 pancreatic cancer. She is cheerful and comforting to others which is amazing. When I asked her how she can cope she says that she has to remain strong for her husband and children and grandchildren! My cousin Maryann is at Memorial Sloan Kettering which is another wonderful hospital like Mayo Clinic. I go with her every 2 weeks for chemo to reduce the tumor. She started 7 months ago and is doing well. God bless all our men and women going through this difficult time
