Why is it important to see a doctor if you have spots on your pancreas ?

Not a medical term: Spots on the panaceas is not a medical term. If you had an imaging study, the radiologist should provide an indication of the diagnosis.

"Spots": on the pancreas is unfortunately not specific medical terminology and doesn't really imply any particular diagnosis. If you have a CT, MR, or US imaging report that describes findings in the pancreas, what does it exactly say?
