People do make it without feeding tube. However I was 43 in great shape and I was determined not to get one. Well, the second round of chemo kicked my but. Although I hated every minute that tube was in my belly, it got me thru the rough 4 weeks. As you mite have read already, it still gets worse after the last rad. To be safe expect 3 weeks of difficult times after rad ends.

Although he might have a few extra lbs on him, this is no time to start a diet. If he is not getting the cals and water. Make an appointment. Just tell him to get it but don't use it. Its not that bad and it will only be in for a couple of weeks.
