Dear Barbara,
My heart goes out to you and your sister with the difficult choices you are facing. I am 54 yrs old and when I discovered I had ovarian cancer back in December one of my grown daughters dug out a book I had purchased some twenty years or more ago for myself and gave it to me once again to read. This book is called "Health Through Gods Pharmacy" by Maria Treben and it provides some very sound herbal remedies for ovarian cancer which I believe would provide a more gentler treatment for your mother at this stage. Because my cancer was only in the first stage and I am otherwise a sturdy person I decided to go the chemo route. I am halfway through my chemo and I am finally breaking down and starting to wonder if I am up to going through too many more treatments. So in your mother's case I would definitely spare her the pain and sickness which comes with this path. God bless you all and have a wonder Mother's Day!
Barbara (great name)
