Martin, prayers are on the way. Tell your wife we are thinking of her.
Check out the Susan G Komen foundation, loads of good info on breast cancer treatments etc. The docs are doing wonderful things for the women (and even men) who suffer from breast cancer. Also lots of good information at the MD Anderson website, Sloan Kettering, and others.
It will be harder on you in some ways Martin, than it will be on your wife. Standing around feeling helpless is absolute agony, so it is great to realize that you CAN help her quite a bit - you can be a shoulder to cry on, a punching bag to rage at, a policeman to make people give her space when she wants to relax, buy her a nice dinner, take her on a trip, handle the hospital paperwork so she doesn't have to fool with it, etc.
Stay tough bud, you and your wife can make it through all this. If there is any info you need or anything we can do don't hesitate to ask
