Hi Connie,
I think a second opinion is a good idea but I think it is difficult to switch the radiation. The chemo should be easy to switch.Sometimes I think the doctors tell us Mom is doing well but they have very strange definitions of doing well. When I knew my Mom was failing more every day the doc kind of patted us and said "oh I dont know why you are upset, she is doing great..everything is fine" Meanwhile, everyday that went by she was weaker and weaker. Hope you are able to find a doctor who will give you better info.
Janet
