My 60 year old mom has recently been diagnosed with stage four lung cancer (never smoked a day in her life) with mets to the lymph nodes, kidney, and brain. She is having stereotactic radiation on the brain tumor and is proceeding with chemo soon. We know that she has only a short time to live, however, we are hoping the treatments will give us some additional time with her. I am mostly concerned with her quality of life and wanting her to have some good days yet. What can we expect from treatments as far as side effects and overall effectiveness?
