Hello and welcome to the site and so sorry to hear about your mom. It is such a hard time and never easy to deal with cancer. I myself have not had radiation but I have had surgery and nodes removed. It is natural that you are scared but I want to try to ease your mind a bit that you have found a wonderful place for information and support! Since I have found a home here I have made many friends who are quickly becoming my extended family. So feel free to ask, vent and/or celebrate!!! We are here for what ever you need. There will no doubt be a great deal of support for you. (probably before I finish writing this to post cause it takes me so long to write something) Looking forward to hearing from you again.
