@judyandchloe - My brother was diagnosed stage 4 lung cancer a year and a half ago. He responded well to chemo and immunotherapy. He has had two "pop up" spots that have been treated with radiation and freezing. Still taking chemo and immunotherapy but evidence of cancer in his body is gone. There is much that can be done today that was not available even a few years ago! He lives a full life- travel, volunteering and loving grandkids. Have hope and faith- we will all end this earthly life sometime. I hope treatments go well for your loved one and the continue onward. BLessings to you and yours!
