where to start.  Mum was diagnosed with non small cell squamous lung cancer stage 4 last year, she has had 2 rounds of chemo, the first round halted the growth of the tumours, further chemo stopped working.  she was offered a trial drug which she accepted, but it failed to work and now the cancer has spread to her liver and kidney adrenal glands.  She has been offered further chemo treatment and she has decided not to have it.  I am really struggling with her decision, I know it is totally her decision, and i can totally see where she is coming from, why put yourself through horrid treatment that may not have any benefit., but I want her to have it in the hope it may be buy her/ussome more time.  I am afraid of how long we will have her for if she doesnt have the treatment.  Does anyone have any experience of life exectancy if she doesnt have treatment. I am worried about everything to be honest, how long she has left, how it will be dealt with, what help can we get etc.how will my dad cope.
