So sad, and he lasted so long with Stage 4 of one of the cruelest cancers. For Alex to have recorded up to October 29, clearly there was a complication. Considering my father died of pancreatic cancer, I am going to make an educated guess that there was a stroke, or a multitude of them. The blood coagulates and this does tremendous damage , not only to the blood flow, but also all the tubes that go from the pancreas to the liver. There are so many complications and he passed at the same age of my father, diagnosed same age, and lasted just about the same , which are on the extreme end of a terminal diagnosis. RIP to a great man
