ca 19-9 results

I was told by by my doctors that I had a 2cm mass in the middle part of my pancreas. They did and EUC and took 8 biopsies of the tumor, plus three vials of blood for the three types of cancer screening. My results came back that all tumor biopsies were benign, however, my CA 19-9 test came back with a reading of 227!! I am shocked and anxious of this result. My bile duct is blocked and I have read that would cause an elevated level on the ca 19-9, but that once the bile duct has been repaired, the level will drop back down to normal. Is this true? I have an appointment with my surgeon Monday, what news can I expect?
