V.B.
I went through breast cancer treatment last year (2010). I finished chemo exactly 1 year ago this week. My son was 19 months old and my daughter was 3 (almost 4) when I was diagnosed. There are so many scenarios with breast cancer that it is hard to say how to help without knowing what kind of treatment she will get. But, in general, just be sure to pray for her and the family (that, quite honestly, helped me SO much to know just how many people I had praying for us). Take the kids off of their hands to help them out. Some days, I was just not physically or mentally able to manage them on my own. Food was a huge help for us. My church provided food for months on end (I didn't necessarily request this....people would just call out of the blue and tell me they were bringing something by....just happened again this week!). One thing that helped me keep people informed without having to tell my story 100 times was to start a CaringBridge site. I journaled everything on there (specific things to pray for, my medical updates, thoughts, feelings, etc) and it was very therapeutic for me and very informative for my family, friends and church family so that they would know how to help or pray without me having to tell them or ASK for help. There is also a guestbook that people can sign leaving encouraging messages. Those were always a great pick me up. I am not one that likes people to do things for me (I'm usually the one doing for everyone else), so accepting help was VERY hard for me, but it was something I just had to get over because there was no way I could have done this alone. Maybe you could help her get a CaringBridge site up and running. They also have a site called CareCalendar.org that allows you to schedule meals, rides, childcare, etc. for the family. Maybe you could be the coordinator for that?
I have just been through this journey and I feel as though I was given this as a mission to help others through it. I'm happy to talk to you or your friend if you have more specific questions. Just send me a PM and I'll get you my contact info. I know how difficult it is, but I'm also living proof that you CAN get through it! I'm cancer free now and life is slowly returning to "normal" (whatever normal is anymore), but this experience has changed me and it will always be a part of me and I am happy to share my experience with anyone who just needs to have a sounding board.
I will be praying for this family.
