I'm sorry to hear that someone so close to you was diagnosed with cancer, it is always a hard thing to go through for everyone.
How did her surgery go, how is she feeling?
I can't speak from experience but I have found a website that has tons of information: http://www.uptodate.com/patients/content/topic.do?topicKey=~wDwC.M5ZjsZk
It also has an abundance of resources to other pages with more information. Hope this helps you!
