Hi there
In sept 07 my father was diagnosed with cancer because of a large tumor on his arm. They ran a battery of tests, CT /PET, bloodwork, MRI's, biopsys, and could not find the primary. Over the course of two months we were told that it was lung, then colon, then finally after an endoscopy the found the primary tumor (that hid so well from everything else) in his esophagus. We were told the good news is they found it and the bad news was they found it. But if I were you I would definalty look into a second opinion. Not because you doctor may be wrong but because you have nothing to loose. They are talking about a big surgery and it is always good to go into something like tha feeling confindent in what you are doing.
I hope that everything works out and that hopefully you can get some answers.
