Hi joe! Welcome! I am sorry we met under these circumstances! I am sorry to hear about your mom. You cannot force anyone to do anything if they do not want to. You can talk to her and tell her how you feel. People hear alot of horror stories about chemo and it can be scary!
My step-mother in-law had back bone cancer and is in remission due to chemo.
Some have luck with it and others do not!
I do wish you and your mom the best on whatever the decision is! You are in my thoughts and prayers!
