[|Human|] My sister was diagnosed with stage 4 lung cancer with mets to the brain stem in June/July 2012. The Brain Stem tumor has gotten bigger since radiation. She is said to be a long-term suvivor and also in the final stages. What type of symptoms should we start seeing? she has lost a lot of mobility, speech, already. this has happened very fast - will it continue at this rate? They tried an infusion treatment called Avastin but it seems to have not worked. She was sent home from Dana Farber on this past Monday with Hospice. Is there any way to find out how bad she will get ? what will it look like?
[|AI|]  Hello. A lung cancer stage 4 with brain metastasis is a pathology of very poor prognosis. The symptoms that she has (loss of speech, loss of mobility)means that the brain metastasis continues to progress. It is possible that with pharmacological treatment (for example corticosteroids) your symptoms improve but unfortunately his sister can only receive palliative treatment and not curative treatment. I'm sorry sincerely inform about state of his sister. I wish you good health.
