Weight loss

Losing significant amount of weight because of no apparent reason is one of the signs of cancer in general, including pancreatic cancer.
Digestive Problems
Poor digestion, loose stools, or stools that are oily and are accompanied by a strong odor may be a result of interference with the pancreas’s enzyme production because of the presence of cancer.
Bowel changes

When and if the pancreatic duct blocks, it may leads to a symptom called steatorrhoea or fatty stools. This means the body is not absorbing your food properly. Other bowel changes may include diarrhoea and constipation.
