My chromogranin has been over 1200 for more than 3 years. Although I have been alarmed about it, my oncologist recently ordered a PET and a CT with contrast that showed basically no change in the pancreatic NET that is responsible for the secretion. While I would prefer for the tumor to be removed, I understand that it is located in such a place that I would have life changing results that might be worse than managing the gastrointestinal symptoms now that are reflected in the high chromogranan and gastrin that are both high. I have learned that the oncologists at Mayo are excellent at monitoring each blood chemistry result but you can always send a message in your health portal about this test result.
