The cancer in my mother's body did kill her in the end but if my mom wasn't so weak in the end she might have survived the hospital visit to continue to do her chemo.
I've heard of people much older thant 72 that have cancer and live many more years.
Money does make a difference. If we could have paid to have her taken care of at home and kept her happy she might have survived.
You can always push doctors and nurses to do things but if they have other patients then they can only give you so much attentions.
We could have full time nurses stay with my mom to make sure everything that could have been done was done. If my mom was at home with us we could have been with her most of the time. The nurse would care for her when we couldn't pay attention.
She would have lived. I know it and I won't allow anyone to tell me different.
