A pancreatic cyst is a fluid-filled pocket in or on the pancreas. With modern scanning they are found by chance in a considerable number of adults, more often with increasing age.
Most are harmless and will never cause a problem. A minority, mainly the mucin-producing types, can slowly turn into pancreatic cancer. The purpose of assessment is to work out which type you have, and then either to stop worrying, to monitor or, for a few people, to operate.
Symptoms
- No symptoms in most people
- Upper abdominal pain that may go through to the back
- Episodes of pancreatitis
- Feeling full, nausea or weight loss with large cysts
- Yellow skin and eyes if the bile duct is compressed
- Newly diagnosed diabetes
Causes and risk factors
Cysts fall into a few groups. Pseudocysts are collections of fluid left after pancreatitis and are not tumours. Serous cystadenomas are benign. Intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms produce thick mucus and carry some cancer risk. The risk is highest when the main pancreatic duct is involved and much lower for small side-branch IPMN. Solid pseudopapillary tumours are rare, occur mainly in young women and are removed. Cystic neuroendocrine tumours also occur.
How it is diagnosed
- MRI with MRCP: The best non-invasive test. It shows the cyst's size, internal walls, any solid nodule and its connection to the duct.
- Pancreas-protocol CT: An alternative that also shows calcification.
- Endoscopic ultrasound with fluid sampling: A needle through the stomach wall draws fluid for CEA, glucose, amylase, cell examination and sometimes DNA markers.
- Blood tests: CA 19-9 and blood sugar or HbA1c.
- Worrisome features: Size of 3 cm or more, a solid nodule that takes up contrast, a main duct of 5 mm or wider, rapid growth or jaundice prompt closer assessment.
Treatment options
- No follow-up: For clearly benign serous cysts without symptoms and for settled pseudocysts.
- Surveillance: MRI or endoscopic ultrasound at intervals from 6 months to 2 years, depending on size and features, for as long as you would be fit for surgery.
- Surgery: Whipple procedure, distal pancreatectomy or, rarely, removal of the whole gland for high-risk or symptomatic mucinous cysts and solid pseudopapillary tumours. This is major surgery that belongs in high-volume units.
- Endoscopic drainage: For symptomatic or infected pseudocysts, through the stomach wall.
- Cyst ablation: Injection of alcohol or chemotherapy into the cyst is still under study and is not standard care.
When it is urgent
Severe constant upper abdominal pain with vomiting, fever with shivering, or yellowing of the eyes with dark urine needs urgent hospital assessment near you. These can signal pancreatitis, an infected cyst or a blocked bile duct.
Travelling to Türkiye for treatment
A visit of 3 to 5 days can provide MRI with MRCP, endoscopic ultrasound with fluid analysis and a review by a pancreatic team. This is worthwhile if you have been given unclear advice or have been offered major surgery and want it confirmed. Planned pancreatic surgery abroad needs 3 to 4 weeks and a firm plan for complications and for enzyme or diabetes care afterwards. Yearly surveillance scans are simpler to do at home.

Frequently Asked Questions
Does a pancreatic cyst mean cancer?
Usually not. Most are benign or low risk. A small proportion of mucinous cysts become malignant over years, which is why some are monitored.
How long will I need scans?
For low-risk IPMN, generally for as long as you remain fit enough for surgery, with intervals lengthening if the cyst is stable.
Is the needle test risky?
Endoscopic ultrasound sampling is low risk. Pancreatitis, bleeding or infection occur in roughly 1 to 3 percent.
Can the cyst be drained instead of removed?
Only pseudocysts are treated by drainage. Draining a mucinous cyst does not remove its lining or its risk.
