What tests diagnose pancreatic cancer?

Diagnosis usually combines CT/MRI (and often EUS) with tissue confirmation when needed. Blood markers such as CA 19-9 support monitoring but do not replace imaging and pathology.

Is CA 19-9 enough to confirm cancer?

No. CA 19-9 can be elevated for other reasons and can be normal in some cancers. Imaging and tissue diagnosis remain the foundation.

Why is “resectability” discussed so early?

Surgery is only useful when the tumor can be removed safely with clear vascular and metastatic assessment. Staging decides whether upfront surgery, neoadjuvant therapy, or non-operative care fits.

Should I get a second radiology review?

For borderline or locally advanced findings, an experienced pancreatic imaging review and multidisciplinary discussion often change the plan.

Pancreatic Cancer Diagnosis

Name: Pancreatic Cancer Diagnosis
Creator: Assoc. Prof. Cengiz Dibekoğlu, MD

High-quality CT (or MRI), bilirubin management, and tissue acquisition define whether a tumor is anatomically resectable.

Pancreatic ductal adenocarcinoma often presents late with painless jaundice, weight loss, or back pain. Pancreas-protocol CT interprets arterial contact and resectability categories; MRI/MRCP and EUS-FNB add detail and tissue. Jaundice may need endoscopic stenting before chemotherapy or to relieve symptoms. Multidisciplinary review prevents both overly optimistic upfront surgery and nihilism when neoadjuvant conversion is possible. Pancreas-protocol imaging and performance status determine whether major resection is even discussed.

Step-by-step overview

1
Clarify the clinical question
What diagnosis is being confirmed and what decision follows?
2
Choose first-line tests
Start with the test that answers the leading question safely.
3
Stage if needed
Add imaging or endoscopy when results would change management.
4
Name limitations
No test replaces exam; false reassurance is a risk.
5
Link to next step
Diagnosis should point to observation, medical care, or procedure.
