Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct. IPMN tumors produce mucus,^[1] and this mucus can form pancreatic cysts.^[2] Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer.^[1] As such IPMN is viewed as a precancerous condition.^[3] Once an intraductal papillary mucinous neoplasm has been found, the management options include close monitoring and pre-emptive surgery.^{[medical citation needed]}
