You asked if anyone had experience with this kind of thing. Not what to do about it. That is good since you have already sought the advise of a provider who knows you and can help you interpret the results.

Contrary to what some would say test results are not as concrete as one would think. They are merely data inputs to someone who from experience, knowledge and training can interpret them. The result often depends as much on the person doing the analysis as the the numbers themselves.

Many things can skew the numbers. For example the lab or lab tech could have made a mistake and you need a retest. It happens. So, experience says you are on the right track. Except I wouldn't post the issue on the supermarket wall as you have done.

Added: Assuming that you indeed have an adenocarcinoma; today that is usually not the end of the world. But, don't cross that bridge until you come to it. Just remember it is a bridge, not a cliff.
