Unfortunately, the likelihood of cure afte bone marrow transplant depends on multiple factors, including the type of leukemia, the severity of the leukemia, the patient's overall health, and the response (or lack of response) to prior leukemia treatments. Therefore, I really cannot answer the first part of your questions (her Hematologist/Oncologist can, hopefully, provide an answer to this quetsion, however).
If the bone marrow transplant is successful, and there are no major complications, she should be just like she was before the transplant.
