Welcome Connie! MD Anderson is the top cancer hospital in the U.S., and probably the best place to get a 2nd or even 3rd opinion, who may have a different opinion than the one which was already given. What one doctor may not be able to treat, another one may, based on their experince, technology. and what is not operable is not always incurable, and hope thats the case with your father. Good luck, and try to relax, although difficult, keep busy, read the OCF information, ask questions.
