Pancreatic cancer

Have a neighbor, Jim, that keeps to himself. I don't talk with him much, he is a racist...and beats on his wife, Taylor. Jim is an alcoholic.
Few years back he was diagnosed with throat cancer. He went for one round of treatment (radiation and/or chemotherapy...might have been both) and decided to walk away from it.
Month or two ago Taylor told my wife that Jim was diagnosed with Pancreatic Cancer. He recently started treatment for it.
Taylor called yesterday, they were at the hospital. Jim had vomited repeatedly. Started having dry heaves etc. Hospital kept him for observation.
I only know of one person that had Pancreatic Cancer, from diagnosis to death was only 2 or 3 months.
Who here has any experience with Pancreatic Cancer? Taylor has some mental health issues...as well as some heart troubles.
