NoBlood

Hi,

My mother has a very small uterine fibroids in her uterus (about the size of a thumb) but it is causing heavy bleeding. She already had D&C to rule out cancer and check what is causing the bleeding.
During the D&C, the doctor almost transfuse blood to her (because she forgot that we are Jehovah's Witnesses). After the D&C, the doctor suggested that if the bleeding don't stop, she needs hysterectomy.
If in the D&C, she has high risk in blood transfusion, is there a greater risk of blood transfusion if she had hysterectomy?
What preparation should we do before the operation to lower the risk of transfusion.
Are there other alternatives aside hysterectomy?

Thanks,
Ananiah
