Hi doctors if a person were to have a tumor on thier pancrease (pancrelipase) what would come first jaundace or dark urine and light stools?

Variable: All the 3 features you have mentioned are caused by obstruction of bile flow, so all 3 would occue together. Besides jaundice, there is usually indigestion, weight loss and abdominal pain which is progressively worse over weeks. If you had any of the above and these symptoms persist a CT scan of the abdomen may be the best way to find out if there is any such possibility(Cancer of Pancreas)

All come together: Jaundice is a consequence of a lesion in the head of t he pancreas. The main bile duct comes from liver to pass in a groove under head of pancreas to enter intestine. When tumor begins in pancreatic duct, 1 cm. of growth outside of duct results in blockage of duct which causes regurgitation of bile back to liver and results in jaundice, dark urine and light stool.
