Hi, Thanks for writing in. Unfortunately cancer of pancreas is one of the difficult ones to treat and your father is in a lot of pain therefore he is getting angry and shouting. Pain in pancreas cancer is severe and does not allow the patient to be comfortable. Please talk to his doctors and request high potent pain reliever medicine to be given at the time of pain. Pancreas cancer is very dangerous and it can be treated only if detected in the early stages. At the moment you have to see that your father does not have pain and give him pain medicine regularly. Please also provide him adequate nutrition and fluids so that his general condition is good. Chemotherapy can be given to extend his life by months. The survival in stage 4 cancer pancreas is 6 months to a year. Therefore pain management is important and if he develops signs like jaundice and abnormal liver function then supportive medicines are required. Please do not worry.
