[|Human|] My ex husband has stage 4 kidney cancer. We dont have a very good verbal relationship.because of this its hard for me to know what to expect for our kids. I know that it has spread and that he has undergone interleukin 2. Now he may be going to have to do radiation also. Any idea on how bad this is? What shouldi tell our kids about his condition?
[|AI|]  Hi. Any stage 4 cancer has poor prognosis and survival around 6 months only. But kidney cancer if not spread in multiple portions to lungs or bones or liver, then targeted molecular therapies are available to keep cancer in control, although it is not curable. So it depends on type of cancer, whether surgery done for kidney or not, response to targeted therapy, his performance status to tolerate therapy etc. If all are good you can expert more than 6 months... probably a couple of years...
