Great big hugs to you. I am the baby although not quite as young as your daughter. Earlier this year my mum had a mammogram and had to go back for more tests she was fine and a few months later I was not fine. I know she has found it hard and she has said it would have been better and easier if it was her. But she has been the best support for me and come to all my chemo and any appointments that I asked her to come to and helped with my little boy. You just have to tell her how much you love her and be there for her. We are much all so much stronger than we think and with your support she will find all the strength she needs to make it through this tough time. Big hugs to her too.
