If a pregnant woman found out that the child inside of her womb had wilms' tumor, what treatment would the doctor give her?

Wait, if possible: A prenatal diagnosis of wilms is quite rare. Unless a biopsy was performed to confirm diagnosis, there are other entities that can look like wilms but are not. Kidney masses can sometimes cause premature labor or distress to the fetus, so it needs to be carefully monitored. After the child is born, then a definitive diagnosis can be made and treatment can be initiated (could be surgery, or more).
