There is a book I highly recommend that has a whole section on dealing with your body image and also for family members who need to understand what having breast cancer and surgery means. It was incredibly helpful to us. You can order it on Amazon. It helped us through the whole process. I hope you can get it and it helps you. Best of luck.
