It works with other digestive organs, including theduodenumsection of the small intestines and the liver.

How Common Are IPMN Cysts?
IPMN are the most commonly identified pancreatic cystic lesion, or PCL, especially as people age.
A 2023 study of 2,114 people aged 50 or older found cysts in 10.9% of those studied.
In most cases, cancer was not an immediate concern.Most people had just one IPMN cyst.
Types of Cysts in the Pancreas
Pancreatic cysts are generally considered either mucinous or non-mucinous.
Different genetic patterns are associated with these types.
Other risk factors may include smoking andobesity.
An IPMN may be found during imaging tests that are being done to look for another problem or condition.
They include:
Backache also occurs in about 10% of people.
Many of the more concerning IPMNs are treated with surgery.
Surgery isn’t always the first-line treatment option for all IPMN, though.
Surveillance is common for other IPMN, depending primarily on its size and where it is located.
In some cases cells that means that the cell is precancerous.
Tubular types may be more concerning.

Summary
An IPMN is a jot down of cyst that can affect the pancreas.
It is one of several cyst types and is known to lead to pancreatic cancer in some people.
Often, there are no symptoms associated with the cyst and it is diagnosed during tests for other conditions.
Sometimes, though, it is associated with pancreatitis and other symptoms.
Treatment typically involves surgery or surveillance (careful monitoring).
Associated cancers may require additional care, including chemotherapy.
