Thanks everyone. I've talked to my husband and we've agreed that getting the peg tube is a good thing in our case. Not just because of emergencies but that it may actually be less traumatic for our kids than to see him choking/gagging etc having difficulty eating.

He had a further CT Scan of his chest, chest x-ray, and full mouth wrap-around x-ray this week prior to seeing the radiologist and oncologist next week.

Is the wrap around x-ray of his mouth just to monitor his teeth or is there some other reason they do that?
