Hoping an Oncology Nurse can help me with my Rehab pt!

Here's hoping that someone here can help me out. I'm a rehab nurse, taking care of a pt with us for rehab (for another dx), but has a hx of ovarian ca with radiation burns to her bilat groin. I'm not sure when she completed her radiation, but last night she raised questions about her burns. They don't quite look like the pictures I see when I check in my textbooks....look almost as if they are drying up--in fact she mentioned that some of the skin is starting to peel. She was wondering if this was normal or not and in general if these burns would ever heal, or if she was just going to be stuck with them--I told her that I would look into it--was hoping you guys could offer some advice. I can't seem to find answers on the likelihood of these burns healing. Thanks for any help you can provide!
