Dad just passed away July 7th in hospice of pancreatic cancer, and I don't think he had a lot of pain. His caretakers were very aggressive in assessing pain or discomfort. Sometimes when people aren't thinking clearly they may not communicate pain as well, but these folks would gently rub his abdomen and say do you hurt here? And the meds always helped. While I can't step inside him and say no he had no pain, I don't think he was ever miserable. Always seemed comfortable when we were with him. It helped me have a little less "fear" of cancer too. I've not really had a fear of dying for years, but feared the pain of dying, and seeing him reassured me that although there may be some discomfort, it's not agony.
