That's an incredibly difficult thing to have to go through.
My mother had three cysts on her uterus and several fibroids on her ovaries and had to have a hysterectomy. However, she was done having children. I know it's expensive, but has she considered having some of her eggs removed and having them frozen? At least that way if down the line she decides to have children she can have another woman carry her baby. Just a suggestion.
I had to have some things done to my cervix that would have prevented me from having children. It was 100% devastating. I was fortunate that I found an alternative solution to my problem. I doubt she has any alternative solutions.
Anyway, I just thought I would throw the freezing her eggs out there. That way she doesn't lose every last chance at having her own blood-child.
