deni,
It looks like your post got lost within Bob's. You should post a new thread. Just click on the "New Topic" button at the bottom of the screen and ask your question again.
Generally speaking, you can only have an area radiated once, but there are some exceptions, esp. with IMRT. For a recurrence after radiation, options are very limited. Chemo is used, but it is usually more of a palliative treatment than it is a curative one.
Repost your question and I'm sure you will get some answers.
Rainbows & hugs,
Rosie
