Light-colored Stools
Bilirubin usually brings the brown color to your stool. Thus, when the bile duct is blocked due to the tumor from pancreatic cancer, it is possible to see gray or light-colored stools. In addition, if the condition prevents your pancreas from producing digestive enzymes, it can be more difficult for the body to digest and break down fat cells. As a result, your stools would become greasy and float, which indicates the presence of excess fat cells. [7]
