The short answer
Pancreatic cancer risk is higher for people who smoke, have long-standing diabetes or chronic pancreatitis, are older, or have a family history or certain inherited syndromes. Smoking is a risk factor you can change.
Smokers are significantly more likely to develop pancreatic cancer than nonsmokers.
Long-standing diabetes and chronic pancreatitis raise risk.
Risk increases with age and is higher with obesity.
A family history or certain inherited syndromes raises risk.

This page explains what raises the chance of pancreatic cancer and what may help lower it.
The simple version
A risk factor is anything that raises the chance of a disease. It does not mean you will get that disease. For pancreatic cancer, smoking is a risk factor you can change. Conditions like diabetes and chronic pancreatitis also raise risk.
Smoking
Smokers are significantly more likely to develop pancreatic cancer than nonsmokers. Quitting smoking is one of the steps the National Cancer Institute lists for lowering cancer risk in general. Ask your care team about help quitting.
Diabetes and chronic pancreatitis
Diabetes raises the risk of pancreatic cancer. Newly diagnosed diabetes, especially in a person without the usual risk factors for diabetes, may also be a sign of pancreatic cancer. If you are newly diagnosed with diabetes and have other symptoms, tell your doctor.
Chronic pancreatitis is long-term inflammation of the pancreas. This inflammation damages the tissue and raises the risk of pancreatic cancer. Drinking a lot of alcohol may increase risk, partly by causing chronic pancreatitis.
Age, weight, and family history
Risk rises with age. Nearly two-thirds of diagnoses are in people 65 and older, though younger people can develop it. Obesity (a body mass index of 30 or higher) is linked to higher risk as well. Having a first-degree relative with pancreatic cancer or pancreatitis raises risk. Up to 10% of cases are linked to inherited syndromes. These include BRCA1 and BRCA2 gene changes, Lynch syndrome, and Peutz-Jeghers syndrome, among others.
Lowering your risk
You cannot change your age or family history. The National Cancer Institute says nothing can prevent pancreatic cancer. But not smoking, limiting alcohol, and keeping a healthy weight and diet can lower cancer risk in general. If you have a strong family history of pancreatic cancer, ask your doctor about genetic counseling.
Screening for high-risk people only
There is no routine pancreatic cancer screening test for the general population. The National Cancer Institute does not recommend screening for people at average risk. People at higher risk, such as those with two or more close relatives with pancreatic cancer, may be screened with tests such as CT, endoscopic ultrasound, or MRI. Screening can also cause harms, including false-positive results, overdiagnosis, and unnecessary invasive procedures. If you fall into this group, talk with your healthcare team.
What to ask your team
- Does my history put me at higher-than-average risk?
- Would quitting smoking lower my risk?
- Does genetic counseling make sense, given my family history?
- What symptoms should I watch for?

Common questions
What raises pancreatic cancer risk?
Key risk factors include smoking, long-standing diabetes, chronic pancreatitis (long-term inflammation of the pancreas), older age, obesity, and a family history or certain inherited gene changes.
How much does smoking matter?
Smoking is a risk factor you can change. Smokers are significantly more likely to develop pancreatic cancer than nonsmokers. Ask your care team for help quitting.
Does diabetes cause pancreatic cancer?
Diabetes raises risk. Newly diagnosed diabetes may also be a sign of pancreatic cancer rather than a cause.
Can I lower my risk?
You cannot change your age or family history, but not smoking, keeping a healthy weight, and limiting alcohol may help lower risk.

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.
