I am a one year survivor. 85% of all abnormalities are benign. Here's a GREAT site for you for information, and they have a wonderful forum much like this one with excellent people to take care of all your fears, needs, and questions. You will make some great friends there too, if you need them. Their chat room is a love and support festival. It's an amazing site! I hope you visit.
