My father had bladder cancer sugery and it was difficult both physically and mentally. We had people stay with him each night in the hospital becasue they are so overworked (nurses) and not attentive enough. If you could find people who she is comfortable with and would stay that is the best thing to do. Even if you take turns during the day so the family could get a break this is a great blessing for those in the family. Once she is home the best gifts are dinners and food. Dad received many home cooked meals and we have a delivery service in CHicago that you can buy certifictes and the loved ones can order from any restaurant in this book that delivers. This is a great way for the person to have what they feel like eating brought to them. My friend had cancer and the set up a schedule for popel to bring food for the family every day for dinner for four weeks until she was stronger.
Hope this helps!
