Thanks for the info everyone!
I forgot to mention that the most recent pathology report indicated that only one lympth node had cancer and that it had grown to a large mass the size of a fist.  The Dr. at MD Anderson said that this node probably had the cancer all along.
Either way it is still worriesome that the RAD was not effective.  I hope MD Anderson can come up with a more effective treatmeant.
We are all very hopeful.   Mom is feeling much better.  I heard the cancer takes alot out of you by your body trying to fight it off.
thanks,
Rick
