[|Human|] Hi, my dad has stage four lung cancer which has spread to his brain. He was diagnosed 7 months ago and was only given weeks to live but has so far kept fighting.  Weve now been told that the cancer has to his lympth nodes. What does this mean? how long would you say he has left?
[|AI|]  Respected user, thanks for using Chat Doctor.come have evaluated your query thoroughly, sorry to hear about the same.* As there is spread to multiple organs, now it is not curable as you know very well by this time, treatment is only & only supportive to take care of symptoms and general supportive care.* Life expectancy can not be uttered by any consultant with the highest efficiency as there are innumerable factors governing it, most important one is destiny written by almighty God which is beyond all the researchers of the world ! Hard to believe, but it is the fact of universe. Wishing him less and less suffering till his last breath. Welcome for further assistance. Regards.
