Can pancreatic enzymes with protease, amylase and lipase hurt or help cancer?

Health fraud. Giving the pancreatic enzymes that help in pancreatic insufficiency (cystic fibrosis, chronic pancreatic scarring) as a cancer treatment is a cynical, cruel fraud. It's often packaged with "detoxification" and coffee enemas. Don't pay money to the people who've tried to deceive you on the thought "what if it did work?".
Probably not. There is no good scientific rationale nor any reliable evidence that taking pancreatic enzymes helps to fight cancer. The exception is patients with pancreatic or some other upper GI tumors where the cancer or the treatment has decreased the amount of pancreatic enzymes the patient can make on their own. In this situation, supplements will help the patient digest food and get needed nutrition.
