Hi Gina, this is so hard for you both.  My husband has incurable lung cancer and without chem and radiotherapy would have died.  There were many times when he was so sick with the treatments that I wondered if we had chosen the right route, he was 71 years old and is now 74 and receives immunotherapy which is palliative.  We still had a quality of life, the children wanted him to live and we could see it was the way forward.  So it will be a struggle but it's his decision.  I've written a daily blog since 2017 on how we coped with it all, there were dark times but more good times.  Your state of mind goes a long way and he should realise that you should make this big decision together with all the facts in front of you.  I wish you well for the future decisions you make, Carol x
