My dad died of pancreatic cancer. He was a health fanatic who never drank soft drinks, didn’t smoke, rarely drank and was not overweight. He ate lots of fruits and vegetable and didn’t eat junk food. The worst thing he did was eat 2 eggs/day and drink whole milk. Diabetes runs in our family. I’m more likely to believe that pancreatic cancer is related to faulty carb/sugar metabolism as well as smoking. Patrick Swayze smoked 4 pack of cigarettes/day. My dad was a bowler and was exposed to plenty of second-hand smoke.
