When I was a kid I used to eat a lot of Candy like taffy skittles etc. Im worried about cancer of the pancreas?

I ate a load of candy and as I got older I smoked tobacco and drank a lot of beer im now 30 haven't smoked or drank for 5 years and for the lats 8 years ive eliminated most bad sugars but i have trouble digesting fat and have low blood sugar issues. Im trying hard to keep healthy I juice carrot juice broccoli juice etc.. It really helps but the pancreas has risk for cancer you have a 60% more chance of it if your drink and smoke compared to a non smoker. Coffee is a huge risk and concentrated sugars all burn out the acinar cells in the pancreas which produce enzymes like lipase amylase etc. Reduced enzymes will cause cancer weight loss and pancreatitis all of this of course takes time like 20 years to produce symptoms average age is 55 for males. Besides my new LifeStyle I feel the damage has been done of course there is nothing I can do until modern science can give me a new pancreas until then any ideas of what else I can do?
