Sally,

Sorry to hear about the return of cancer for your brother.
You say he knows very little about what he will be going through. He needs to talk with his Dr. and ask all the questions he needs to know about it. I am sure it will help him to reduce the anxiety of it. We all were scared when we first went into this. So he is not alone.

Keep us posted. Ask questions, I am sure someone here has went through the same thing or something like it. Use the search to help you find more information.

Take care,
Diane
