Hi and welcome to the BCC discussion forums. I am sure your fellow forum users will be along soon with hints and tips on how you can help your daughter through this. I have put for you below links to a couple of BCC's publications you and your wife might like to read which may make things a little clearer on what to expect while your daughter is going through treatment and afterwards. The second link is aimed a partners of those going through treatment but I am sure most of it will relate to you and your wife while trying to support your daughter and her family.

Hello. I am 69 year old father. My daughter had a mastectomy and is waiting to start chemo, thank goodness there was no secondary tumour. Anyone diagnosed with cancer must feel terrified, if it was me I dont know what I would do. My wife and I are still in a state of shock. My daughter has 3 children all under 10. We are trying to find out as much as we can about cure rates and what to expect.. We are of course helping out as much as we can. My thoughts go out to you all.
