The last food we are going to talk about is fish. Fish contains high levels of fats and as we have already seen a lot of fats causes the pancreas to overwork which is fatal. In addition to having high levels of fats, fish also have a strong odor. People with pancreatic cancer often have an episode of nausea and taking foods with strong odor like fish will only set it off. Eating fish will increase the side effects of the cancer as well as cause discomfort. Avoid eating fish as much as possible if you have pancreatic cancer.
