@Reminiscence- I'm sorry for your loss. Pancreatic cancer symptoms are often confused with other conditions. Because the pancreas provides insulin, some of the early signs of pancreatic cancer can look like signs of diabetes. That's what happened with my uncle. He started having problems keeping his blood sugar under control, then he had severe abdominal pains and digestive issues. His family doctor didn't suspect pancreatic cancer at first, so he put my uncle on the same treatment plan as type 2 diabetics.
By the time my uncle received the pancreatic cancer prognosis, he was at Stage II. An oncologist put him on an experimental pancreatic cancer treatment, and miraculously he went into remission. He was one of the lucky ones, because the oncologist told us that the average pancreatic cancer life expectancy after diagnosis was 6 months to 2 years.
