Need more info: Sorry to hear about your father. There is not enough information to answer this. Please ask the question again with more details. What is the stage of your father's lung cancer (or did you mean stage 1) and also the stage of his prostate cancer?

It varies: Most likely the lung cancer will be the cause of his death and predictably within months not years - but that is an average and some patients live years with Stage IV lung cancer so prediction is uncertain
