[|Human|] My father in law had a melonoma cut out a couple of years ago, it has spread to lungs, liver, and brain, it is obviously terminal, today he has been unable to eat, he is diabetic, and has been throwing up which has been a dark brown colour, it he getting near the end ? Thanks
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Melanoma is rapidly spreading cancer with very poor prognosis.  He has spread in lung and brain, so it is stage 4 cancer.  Chemotherapy is the treatment of choice.  It is only palliative care.  It can not cure the disease.  Prognosis remains very poor despite treatment.  Life expectancy is not good.  One should not expect much from this. Sorry to say but it is fact. 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.
