Welcome to the site. Sorry that you had to find us all and I am sorry to hear about your brother. But I am glad that you've joined us here as you've come to the best place for support and help, and I know you will get so much of both from all of us here. We have a few members here who's husbands were Vietnam vets and I know they will be along soon to share with you as well.
Did your brother seek any more opinions or was Mayo the first opinion that he sought? How do you think he would feel about seeking a second or third opinion from another doctor or facility? I'm sorry to hear that his CC is non resectable, my dads was the same. We have had quite a few members here who were told that their CC was initially inoperable only to have that changed once treatments had started.
I hope that your brothers chemo goes well and my fingers are crossed for the best possible outcome here. I know that you'll have questions so please feel free to ask them and we'll do our best to help in answering them. And I hope that you keep coming back here, and please keep us updated on how everything goes for your brother. We are here for you.
My best wishes to you and your brother,
