<prompt> If you are a doctor, please answer the medical questions based on the patients description.my aunt has brain tumour stage four she did her third surgery about two months ago when she went back for a check up they did a cat scan an said the tumour grew back an there is nothing they can do about it so i would like to know how long she has to live  <response>: Hi, dairy have gone through your question. I can understand your concern. Life expectancy and prognosis depends on type, stage and behavior of your brain tumor. It is stage 4 cancer so irrespective of type prognosis remains poor. No surgery is possible in this case. Palliative radiotherapy is the only option. And life expectancy is very low despite treatment. 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.
