Still in the hospital

Dad remains in the hospital for another day. They ordered a CT scan to check his lungs. Not sure what they are looking for except to see if the cancer is back in his lungs now. He remains lethargic and won't eat. He told the nurse to get out with the lunch tray. He's pretty down right now. He can't (or doesn't want) to hear much of anything. He says he has no pain.
We probably won't get the scan results until tomorrow morning. They were supposed to do the scan at 3:00 but they now said it will be 5:30. Hurry up and wait. That's how it goes at the hospital. Will update later if we hear anything.
