My mother is told she has less than a year due to her cancer, but she's still not sick. When does that happen?
With stage 4 lung cancer, very few patients will live one year or more and so doctors give that warning. As for when will someone with stage 4 lung cancer show signs of illness, that is hard to answer. Many people look fine for a while and then start to get short of breath. That shortness of breath can proceed rapidly or slowly depending on where the cancer is. There may also be pain or not. There is no way to really predict when your mother will start to have symptoms but with stage 4 lung cancer, it is likely to be sooner rather than later and proceed fairly quickly over months and not years. There is also a possibility for sudden events like blood clots to occur, however that can rapidly speed up the progression of illness.
