Medical researchers remain unsure of the exact causes of pancreatic cancer, but they have discovered many factors that increase the risks, including genetic makeup and lifestyle. The fact that a person has a higher risk profile for some reason does not mean they will certainly get the disease. The links are not well understood, but the statistics do suggest some correlation.

Here are 10 causes of pancreatic cancer.

1. A Disease of the Elderly

Everyone hopes to reach old age, but this period of life also brings its health challenges. Unfortunately, pancreatic cancer can be one of those challenges. Figures show that the disease is relatively uncommon in people under the age of 50, and about half of all new cases involve people aged over 75.

These statistics suggest that something in the aging processes, possibly a weakening of the immune system, increases the risks of developing the disease. Hopefully, future research will help doctors understand this process better and perhaps develop preventative treatments.
