[|Human|] 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
[|AI|]  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.
