My 92 year old Father was admitted to hospital with pneumonia and significant weight loss, and difficulty swallowing. The second day there he aspirated his pureed food, and the Dr.ordered a ct scan. The results were interpreted as lung emboli, and a mass in his esophagus, and carcinatomas in his abdomen. The Dr. won't do a biopsy to confirm the mass is cancer. Is one ct scan enough to be certain he has cancer, what if the interpretation is not correct? Should he have a biopsy, or another ct scan to confirm the diagnosis? I have been with him in his hospital room 24/7 except for going home to shower every few days and he has fought off the pneumonia, but the Dr. won't put in a feeding tube because he says it will only feed the cancer. My Father is coherent and desperately wants to recover, but with no feeding tube, there is no hope. He says he has no pain, but they are now giving him dilaudin. I just want to know if one ct scan is enough to justify this denial of nutrition, and administration of dilaudin that keeps him asleep 24/7 ?
