I found out that i had the same cancer 1 year ago. It is not a good cancer there is not much they know. But has helped me is having a positive out look dont settle with what they have to say. I did 2 surgerys and went six weeks of chemo and radiation then went 12 more weeks of just chemo it was gone for 4 months and now is back. So i am undergoing chemo again. tell your mom to ask about having it all removed before she starts treatment there are a bunch of diffrent types of surgery they can do. Look in to cyber knife also ask about chemo and if the 5FU pump would work. she will get verry tired and not want to get out of bed but the best thing that helped me was family and friends. dont let her do the reserch have someone else do it because everything that she will read will say nothing good about the out come.
by best wishes to you and if you need to talk I am here.
