Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
Your uncle passed away with pancreatic cancer, Diagnosed only two weeks before death. he had
jaundice,
malaria,
typhoid, along with this. He had diabetis and
hypertension. After 6 hours of death a dilute blood like substance started flowing from his nose and mouth.
Probably the sequence is different, in the begening he is diagnised as typhoid , malaria, and jaundice, this sequuence is common.
Finally it might be a false diagnosis and pancriatic cancer is the final diagnosis, there might be co exesting previous diseases, but neither these nor the treatment givenfor that can't lead to the pancriatic cancer.
Regarding bleeding the hypertension or the jaundice or cancer can predispose to the bleeding, and followed after the demise.
I hope i have answered to your satisfaction.
