I've never had rads but will be praying that it goes well for you. My friend had them two years ago and it went very well and she is doing extremely well even though she had a very aggresive form of cancer and 4 positive lymph nodes. She has had no problem with recurrence. She did A/C, Taxol and then rads.
Keep up informed!
