Hi, dear I have gone through your question. I can understand your concern. Your dad has pancreatic cancer and it is inoperable so it must be terminal stage cancer. coughing of blood is common and it is not a good sign. His prognosis is poor and life expectancy is not good. Sorry to say but it is fact. No treatment should be given for pancreatic cancer. Morphine or other pain killer or nerve block can be given for symptomatic pain relief. Hope I have answered your question, if you have any doubts then contact me at bit.ly/Drsanghvihardik, I will be happy to answer you. Thanks for using health care magic. Wish you a very good health.
