<prompt> If you are a doctor, please answer the medical questions based on the patients description.my daughter inlaw was diganosed with stage 4 breast cancer over a year ago she had chemo for five months and everythinng went well and then she had a seizer and found to have brain metsshe had 20 full head radiation treatmentsshe is doing ok but its been about six mo since radiationshe dont eat good and is very thinwill this all go away and can we count on a full recoverycould she be cured?  <response>: Hi, Metastatic breast cancer is not curable. Brain metastasis itself has very bad prognosis. Radiation is the only treatment surgery has also role in limited cases. Now you have not mentioned the hormone receptor status. Probably she is on antiestrogen. Anyway, the treatment at this stage is complex. And brain metastasis can cause nausea, vomiting headache. Anorexia is due the disease itself. You have to try your best to feed her. No specific medication will be much helpful to increase the appetite. As long as she can maintain nutrition, she can fight the disease.
