If the can't get chemo anymore then you will see where it leads him, a few months with out chemo, everyone is different but he is stage 4, and 6cm tumor, My husband was the same and he was 4 yrs and 3 months before he passed. He had everything possible to help but in the end there was no more.
I just wished I was more prepared to realize he was not going to get better, I was sure we would because he was such a fighter, but don't forget everyone is different. I will pray for you , and speak open and frank with your Dr's and tell them of your fears and what can be done, or is there not anything ? I didn't want to hear there is nothing else we can do. But they were really be kind. they did not want to see me try to do everything and anything, so I had to help my love get ready to leave, I had to be strong for both of us. I will pray for you.
