The short answer
Pancreatic cancer is staged by how far it has grown and spread, often described as resectable (removable by surgery), borderline resectable, locally advanced, or metastatic. Whether surgery is possible is a key question.
Staging describes how far pancreatic cancer has grown and spread.
A key question is whether the cancer can be removed with surgery (resectable).
Categories include resectable, borderline resectable, locally advanced, and metastatic.
Whether surgery is possible depends on whether nearby blood vessels are involved.

This page explains how pancreatic cancer is staged and why doctors also ask whether surgery can remove the tumor.
Two systems, used for different purposes
Pancreatic cancer is staged in two ways. Each one serves a different purpose. The AJCC (American Joint Committee on Cancer) system assigns a stage from 0 to IV. It uses tumor size, lymph node involvement, and distant spread. NCI's clinician summary uses the 8th edition. Doctors also describe pancreatic cancer using a resectability category, which says whether surgery can remove the tumor. The categories are resectable, borderline resectable, locally advanced, and metastatic. This second system exists for a reason. For pancreatic cancer, whether surgery can remove the tumor matters as much as the formal stage number. Sometimes it matters more.
Stage 0: the earliest point
Stage 0 is carcinoma in situ. NCI's clinician summary says this includes high-grade dysplasia without invasion.
Stage I: small and confined
Stage I means the tumor is still confined to the pancreas. It has not spread to lymph nodes or distant organs. Doctors split this into two groups. IA means the tumor is 2 centimeters or smaller. IB means it is larger than 2 and up to 4 centimeters. A tumor without blood vessel involvement is called resectable. That means surgery may be able to remove it.
Stage II: larger, or with limited node spread
Stage II also has two parts. IIA means a tumor larger than 4 centimeters. It is still confined to the pancreas, with no node involvement. IIB means a tumor of any size that has spread to nearby lymph nodes. One to three nodes can be involved. Ask your team whether your tumor is resectable and whether chemotherapy would come first.
Stage III: locally advanced
Stage III has two possible meanings. The cancer may have spread to four or more lymph nodes. Or the tumor may involve the celiac axis, the superior mesenteric artery, or the common hepatic artery. Either way, it has not spread to distant organs. This is where the resectability category becomes especially important. NCI describes borderline resectable tumors as ones with blood vessel involvement or a high risk of cancer cells left at the edge after surgery. Locally advanced tumors have local invasion that rules out surgery. Ask your team which group applies to you.
Stage IV: spread to distant organs
Stage IV means the cancer has spread to distant sites, such as the lung, liver, or the lining of the abdomen (peritoneal cavity). This is metastatic cancer. Treatment focuses on drugs that work throughout the body and on controlling symptoms. Ask your team whether surgery has any role.
Why resectability matters as much as stage
Two people can carry the same AJCC stage number. They can still face very different treatment paths. The difference often comes down to where the tumor sits relative to major blood vessels. NCI says that when surgery can completely remove the tumor, you have the best chance of long-term survival. NCI's clinician summary says chemotherapy before surgery is increasingly recommended, especially for borderline resectable cancer. For locally advanced cancer, NCI calls chemotherapy the primary treatment. For metastatic cancer, ask your team about the goals of treatment.
What to ask your team
- What is my AJCC stage, and separately, is my tumor considered resectable, borderline resectable, or unresectable?
- Would chemotherapy before surgery improve my chances of a successful operation?
- If surgery is not possible now, could it become possible after other treatment?
- What does my specific stage and resectability status mean for my treatment plan and timeline?

Common questions
How is pancreatic cancer staged?
It can be described by numbered stages (0 to IV) and, practically, by whether it can be removed with surgery: resectable, borderline resectable, locally advanced, or metastatic.
What does 'resectable' mean?
Resectable means the cancer can likely be removed with surgery. Borderline resectable means blood vessels are involved or there is a high chance cancer cells are left at the edge after surgery. Ask your team whether treatment first could change the plan.
What is metastatic pancreatic cancer?
Metastatic means the cancer has spread to distant organs, such as the liver or lungs. Treatment focuses on drugs for the whole body and on controlling symptoms. Ask your team whether surgery has any role.
Why does the stage matter so much?
NCI says complete surgical removal gives the best chance of long-term survival, so whether the cancer is removable is one of the most important questions.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
