Donna, my husband has lung mets, too. The possibility that the lesions were there already but too small to be picked up by CT scans when the cancer was first diagnosed has also been mentioned. I asked both the RO and Mo what the pronogsis was and while my husband did not want to know (still does not want to know), the doctors were able to tell me with his permission. My husband is now in a phase 1 drug trial. We have no idea yet if it is helping but he is due for a review in a week's time. Another person you might be able to talk to is your hubby's GP who should have been receiving reports from the specialists, but I would think that you will also need to get his permission for that.
