A CT scan or magnetic resonance imaging (MRI) may unexpectedly reveal a pancreatic cyst. Seeing the words "pancreas" and "cyst" on an imaging report can immediately raise one worrying question: "Could this be cancer?"
However, pancreatic cysts come in different forms, and a pancreatic cyst does not automatically mean pancreatic cancer.
A pancreatic cyst is a fluid-filled lesion within the pancreas. Different types have different causes and clinical significance. Some may develop after pancreatitis, while others are pancreatic cystic neoplasms. Certain cysts are considered low risk and may remain stable for years, while others require closer surveillance.
For this reason, doctors do not assess risk based on the word "cyst" alone. Features such as its size and appearance, the presence of a solid nodule and whether the pancreatic duct is dilated may all affect the next step.
Depending on the findings, further MRI, endoscopic ultrasound or regular imaging surveillance may be recommended. Persistent upper abdominal pain, recurrent pancreatitis, jaundice or unexplained weight loss should also prompt further assessment.
A pancreatic cyst does not necessarily mean cancer, but the absence of pain does not mean it can always be left unattended.
