What does exclusion of pancreatic cancer mean?

Answer 1

When making a diagnosis in medicine, physicians often first make a list of possible conditions before deciding upon a final diagnosis. This list of possibilities is called a differential diagnosis. As the physician records a history of a patient, performs a physical exam, and reads laboratory tests, items can be added or removed from the differential diagnosis. When tests reveal sufficient evidence against a particular disease or condition, that condition can be removed, or excluded, from the differential diagnosis. So exclusion of pancreatic cancer means that tests and questions have been asked that have led to the conclusion that pancreatic cancer is no longer considered as a likely diagnosis.
