Diarrhea
Diarrhea can occur with many types of pancreatic cancers. It can also be a sign of a tumor called a VIPoma. This uncommon pancreatic tumor releases a substance called vasoactive intestinal peptide (VIP), which sends more water into your digestive system. Excess water in your intestines can lead to severe, watery diarrhea. Pancreatic cancer can also prevent you from properly absorbing nutrients from the foods you eat, which can also trigger diarrhea. Visit your doctor immediately if you observe any change in bowel habits.
