2. Jaundice
Tumors of the pancreas often block the duct that releases bile into the intestine, called the common bile duct. In turn, bilirubin builds up in the blood stream and causes a condition called jaundice.
If you have jaundice, your skin and eyes will turn yellow and you may experience intense itchiness. There are a lot of potential causes of jaundice that are not cancer, but jaundice should always be checked out by a doctor. The underlying cause must be treated in order to resolve it.
