Pathology
In brief: Limited
This is an abnormal protein that is often present in people with a variety of cancers of the gut, particularly pancreatic cancer.
It is not a good screening test in the absence of a known mass. If positive, results should drop on removal of the tumor and will probably rise again as an early warning of tumor recurrence.
