Hi my husband was diagnosed with stage 4 lung cancer in June..as his health is so poor having severe copd and 3 previous heart attacks he is unable to have any treatment..all he does all day is sleep! He's not even awake for an hour then hes back to sleep..Im just concerned as his quality of life now is very bad and hes not able to do anything or go anywhere other than hospital appointments..is this normal or something to worry about..its so hard to watch this every day
