[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  She has bone cancer and metastasis in brain and liver.  So it stages 4. No treatment will cure the disease.  Chemotherapy is helpful just as palliative treatment.  Despite treatment prognosis remains poor.  Life expectancy is just few months So consult your doctor and plan accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
