My CA went from 43 the first time I was tested a yr prior to the abdominal
pain, 37 the month prior to the abdominal
pain to 66 when it turned out my lipase was elevaed. My lipase went down but remained slightly elevated for at least 2 wks (it has not been checked since), my CA 19 had gone down 10 points.
I have had the following tests during the past year: CT scan, MRI, MRCP, EUS and another EUS 6 months later- all 100% clear.
