Smoking and Pancreatic Cancer Statistics 2026

If you are looking for smoking and pancreatic cancer statistics, the headline is consistent across sources: people who smoke have roughly twice the risk of pancreatic cancer, and about one case in four to five is linked to smoking. The more hopeful half of the data is that the extra risk falls after you stop. This guide sets out the relative risks, the share of cases linked to smoking, the latest US incidence and survival numbers with their year ranges, and what the studies say about quitting.

Smoking and pancreatic cancer statistics: about twice the risk, about a quarter of cases

Pancreatic cancer is relatively rare, but it is serious, and smoking is one of its most important changeable risk factors. The American Cancer Society states that “Smoking is one of the most important risk factors for pancreatic cancer.” It adds that the risk is about twice as high among people who smoke compared with people who have never smoked. It also says about 25% of pancreatic cancers are thought to be caused by cigarette smoking (see the ACS pancreatic cancer risk factors page).

The same page adds a line that matters for anyone thinking about quitting: “It’s never too late to stop smoking, since the risk of pancreatic cancer will drop once a person stops smoking.” The sections below show the numbers behind those statements, including what each study measured. For the wider picture of smoking-related cancers, see smoking and cancer statistics and the cancers smoking causes.

How much smoking raises the risk of pancreatic cancer

Three sources give slightly different numbers because they combine different studies. All point the same way:

The Iodice meta-analysis (Langenbeck’s Archives of Surgery, 2008) combined 82 studies published between 1950 and 2007. Its authors conclude that smoking cigarettes causes a 75% increase in the risk of pancreatic cancer compared with non-smokers (see the PubMed abstract). Note that the confidence interval for former pipe and cigar smokers is very wide (0.68 to 2.45), so that single figure should not be over-read.

Cancer Research UK adds that risk increases with the number of cigarettes smoked per day and with the duration of smoking. Cigar-only smoking raises risk to a similar extent as cigarette-only smoking in a pooled analysis, while pipe-only smoking was not associated with pancreatic cancer. On smokeless tobacco the sources differ: the ACS says its use increases risk, while Cancer Research UK notes a meta-analysis of snus users with about 80% higher risk, though it adds that a pooled analysis showed the evidence is mixed (see Cancer Research UK pancreatic cancer risk factors).

What share of pancreatic cancers is linked to smoking

Different bodies estimate this share in different ways, so the figures are not identical:

• United States: about 25% of pancreatic cancers are thought to be caused by cigarette smoking (American Cancer Society).
• United Kingdom: 22% of pancreatic cancer cases are caused by smoking (Cancer Research UK, page last reviewed 14 June 2018 for the tobacco section).
• Modeled example: Iodice and colleagues estimate that in a population where 30% smoke, about 20% of pancreatic cancer would be explained by smoking. That is an illustration of the method, not a measured national figure.

Put simply, smoking does not cause most pancreatic cancers, and many cases occur in people who never smoked. But it accounts for a share large enough that, if everyone stopped, a meaningful number of cases would be avoided.

Pancreatic cancer in numbers: incidence, deaths and survival

The US National Cancer Institute’s SEER program publishes the following figures for pancreatic cancer in all patients (not only smokers), each with its own year range (see the SEER cancer stat facts: pancreatic cancer):

• Estimated new cases in 2026: 67,530, which is 3.2% of all new cancer cases.
• Estimated deaths in 2026: 52,740, which is 8.4% of all cancer deaths.
• Rate of new cases: 13.9 per 100,000 people per year, age-adjusted, based on 2019 to 2023 cases.
• Death rate: 11.3 per 100,000 people per year, based on 2020 to 2024 deaths.
• Lifetime risk of diagnosis: approximately 1.7% of men and women, based on 2021 to 2023 data.
• Median age at diagnosis: 71 (SEER 21, 2019 to 2023).
• 5-year relative survival: 13.7% (SEER 21, excluding Illinois, 2016 to 2022).

Survival depends strongly on how far the cancer has spread when it is found:

SEER cautions that survival statistics describe large groups and cannot predict what will happen to an individual patient. Because only a minority of cases are found while still localized, modifiable risks such as smoking get a great deal of attention.

How to read these numbers

Three distinctions help when you compare figures from different pages:

• Relative versus absolute risk. A relative risk of 1.74 means 74% higher than the comparison group, not a 74% chance. Pancreatic cancer is uncommon overall: SEER puts the lifetime risk of diagnosis at approximately 1.7% for men and women combined, so even a doubled relative risk applies to a small starting number. Neither figure predicts what will happen to one person.
• Risk versus share of cases. A relative risk compares smokers with non-smokers. The 25% (US) and 22% (UK) figures describe how many cases in the whole population are attributed to smoking. They depend on how many people smoke, which is why they differ between countries and decades.
• Different studies, different years. The Iodice meta-analysis covers studies published from 1950 to 2007. The Cancer Research UK tobacco section was last reviewed on 14 June 2018. The SEER page carries 2026 estimates. Newer research may refine the estimates, but the direction has been stable for decades.

Age also matters. The American Cancer Society notes that almost all patients are older than 45, that about two-thirds are at least 65 and that the average age at diagnosis is 70, in line with SEER’s median of 71. That means the benefit of quitting accrues over many years, which is a reason to stop earlier rather than later.

What happens to the risk after you quit

Two lines of evidence describe the decline:

• The Iodice meta-analysis found that former smokers had a relative risk of 1.2, much lower than the 1.74 for current smokers, and that for former cigarette smokers the risk remains elevated for a minimum of 10 years after cessation.
• Cancer Research UK reports that, in a pooled analysis, pancreatic cancer risk in people who quit smoking 20 years ago is similar to that of never-smokers.

Together these suggest the risk falls gradually and can reach the level of never-smokers after about two decades. Individual results will vary, and quitting also lowers the risk of lung cancer and many other diseases; see lung cancer statistics and our piece on what percentage of smokers get lung cancer. The sooner you stop, the sooner the clock starts.

Other risk factors besides smoking

Smoking is one of several factors, and most people with any risk factor will not develop the disease. According to the American Cancer Society, other factors include excess body weight (people with obesity are about 20% more likely to develop pancreatic cancer), diabetes (more common in people with diabetes, mostly type 2), chronic pancreatitis, heavy workplace exposure to certain chemicals, age, a family history and inherited gene changes, which may cause as many as 10% of pancreatic cancers. It notes that chronic pancreatitis is often seen with heavy alcohol use and smoking. Our guide to smoking and pancreatitis covers that link.

Cancer Research UK reports that 12% of UK pancreatic cancer cases are caused by overweight and obesity, that risk is 15 to 19% higher in people who drink 24 g or more of alcohol a day (3 or more UK units), and that risk is 62 to 76% higher in people with a first-degree relative with the disease. None of these cancels out the benefit of quitting, and smoking is the one most directly in your control.

Using the numbers to start

Risk statistics do not tell you what will happen to you, but they can help you decide what to do next. iQuit is free on Google Play and the App Store and includes disease-risk insights for 11 conditions and a health-recovery timeline, along with craving tools, an AI coach and a mood journal. These features are educational, not a diagnosis. If you have symptoms or a family history that worries you, speak to your doctor. For what tends to work when you quit, see quit success rates by method.
