Hi there,
Welcome to the site. Sorry that you had to find us all here and I am sorry also to hear about your sister. But I am glad that you have joined in with us all here as you are in the best place for support and help and will get a load of each from everyone here.
Have you used the search forum function at the top of the page to search for posts that will help find experience from people in the Buffalo area? If not that would be something you could try and we also have this thread here that was created by our members as well. It has info about doctors, oncologists etc that have treated some of our members and their loved ones and was created by the members here.

Please keep on coming back here as well. You are not alone in this now, we are here for you and we care.
My best wishes to you and your sister,
Gavin
