Carol....I recall a conversation with a surgical oncologist who had made a similar comment. But, as we have seen on this board many patients do not show any elevated tumor markers until the later stage of this disease. I think that although, the tumor markers are of high value, all other symptoms of the disease are prevalent when diagnosing and treating this cancer. The conversation today focused on the value of tumor markers and that only around one hundred protein markers have been identified although, there are over one thousand that have not yet been specified.
