I would have to agree with both Eric and David on this one. In my 7 years here I have never heard of anyone getting a 4 week break in radiation. My oncologist at UCSF and wrote the book on IMRT didn't like me missing treatments for any reason, well except for a few time when the machine went down.

I lost over 61 lbs and literally crawled into treatment the last few weeks - they did cut one Cisplatin treatment because I had such a severe reaction. I also made 2 trips to the ER. RT/Chemo is no walk in the park.

How is he faring? How are the mouth sores? Neck burns? Pain management effective?

I believe that the main benefit of RT is the accumulative effect and also the fact that the effects keep on going, for a time, post Tx. Maybe that's his logic?!? Maybe his bloodwork numbers are so poor he may have an unneccesary risk from completing treatment at this time. I would grill the RO about his decision and what the risk/benefit could possibly be from the delay. It is very unusual. It's the longest break in Tx that I have heard of.
