Your brother is a strong person and has been fighting cancer of esophagus for 7 months now. Pain is a subjective sensation and no two people can experience the same degree of pain. In your brother, it is possible that the cancer in the esophagus is irritating surrounding sensory nerves that carry pain sensation. This pain is being transmitted to the higher center in brain and that is why he needs morphine to suppress it. A fight with cancer is allowed to go on as long possible. Your husband might have had a cancer that was less infiltrating the nerves and his pain tolerance was good. In my opinion, cancer patients with stents can live up to over a year on semi-solid and liquid diet and if the cancer does not infiltrate fast inside the stent lumen. Please allow as much pain relief possible after discussing with his doctor,
