Pancreatic cancer remains one of the most challenging cancers to diagnose early, with almost half of patients presenting with metastatic disease. Now, a growing body of evidence indicates that this deadly cancer has been steadily on the rise, particularly in younger individuals who may not even realize they are at risk.
A recent survey, for instance, found that 33% of 1000 respondents younger than 50 years believe that only older adults are at risk for pancreatic cancer, and more than half said they wouldn’t even recognize the early signs and symptoms, which include unexplained weight loss, fatigue, jaundice, abdominal pain that radiates to the back, nausea, and vomiting.
These survey findings allude to a bigger challenge: Identifying the disease
remains elusive against a backdrop of these increasing rates and nonspecific risks and symptoms.
Currently, only about 15% of pancreatic cancers are caught at a localized, resectable stage, when 5-year survival rates are highest at 44%. But most are found later, after symptoms arise, and at this point, the 5-year survival odds plummet —16% for regional disease, 3% for distant, and 1% for stage IV.
“This disease is too often a silent killer, with no symptoms until it has progressed to less treatable stages,” said survey co-author Zobeida Cruz-Monserrate, PhD, from The Ohio State University Medical Center in Columbus, Ohio.
Rising Rates
Since 2001, rates of pancreatic cancer have steadily increased by about 1% annually, and this increase appears greater among younger individuals, especially women.
A recent study in Gastroenterology, for instance, found that, while overall rates of pancreatic cancer among people aged 15-34 years remained low (0.3% in women and 0.2% in men) between 2001 and 2018, the average annual percent change in this age group was considerably higher than that for older individuals — 6.45% for women and 2.97% for men compared with 1.11% for women aged 55 years and 1.17% for men aged 55 years. Another recent analysis, published in Annals of Internal Medicine, reported similar increased rates in men and women aged 15-39 years between 2011 and 2019.
Although more than 90% of cases do occur in those 55 years or older, “we’re now seeing this disease in people who are in their 40s much more regularly,” Cruz-Monserrate said. “This is a concerning trend — and more research is needed to learn why.”
But it’s early days. Studies so far indicate that early onset pancreatic cancer tends to be even more aggressive, but the “underlying reason is not yet clear,” researcher wrote in a 2025 review.
Some evidence indicates younger individuals may have distinct molecular characteristics, whereas other research shows younger and older patients have similar genetic profiles. Younger patients may also be more likely to smoke, drink more, and delay seeking medical attention as well as experience delays in being diagnosed by physicians, the authors explained.
Catching It Early
Given the rising rates, early detection is especially important.
There are some known genetic and medical risk factors for pancreatic cancer. About 10% of these cancers are linked to heredity risk or genetic markers, including BRCA1 and BRCA2 or Lynch syndrome. People with chronic pancreatitis, type 2 diabetes, obesity, or with a family history of pancreatic cancer face an elevated risk.
Lifestyle factors can play a role as well. Alcohol consumption, a poor diet that includes red or processed meat, and smoking increase people’s risk for pancreatic cancer. In fact, smoking leads to a twofold higher risk compared with not smoking.
However, uncovering pancreatic cancer from these factors alone can be like “finding a needle in a haystack,” said Srinivas Gaddam, MD, associate professor of medicine and head of the pancreatic cancer screening and early detection program at Cedars-Sinai Medical Center in Los Angeles.
One strategy to help detect the disease earlier would be to screen more.
The latest guidance from the American Cancer Society suggests that people with a genetic predisposition or a family history of pancreatic cancer could benefit from annual surveillance with endoscopic ultrasound or MRI.
But the US Preventive Services Task Force currently recommends against routine screening of average-risk asymptomatic adults. The task force found no evidence that screening for pancreatic cancer improves disease-specific morbidity or mortality or all-cause mortality.
“The absolute incidence in younger people is far too small to make screening beneficial,” explained The Lancet Gastroenterology & Hepatology editors in a 2023 editorial.
In fact, more screening could lead to overdiagnosis, a concern reinforced by the recent study in Annals of Internal Medicine. The analysis found that much of the observed increase in early-onset pancreatic cancer stemmed from the detection of more small, early-stage endocrine cancer, rather than pancreatic adenocarcinoma, whereas mortality from the disease remained stable over the study period.
Recent findings do “suggest the potential for overdiagnosis and overtreatment, particularly in cases of indolent pancreatic neuroendocrine tumors,” Gaddam said.
Gaddam has observed an increase in both adenocarcinoma and neuroendocrine tumors in the clinic and in his research, especially in women younger than 50 years, but he noted these early onset diagnoses do remain rare.
Staying Vigilant
As the understanding of pancreatic cancer risks and symptoms evolves, ensuring that patients, especially younger individuals, recognize the warning signs, without causing alarm, remains a challenge.
The disease “presents more advanced in younger patients, but symptoms are so nonspecific,” said Randall Brand, MD, director of the Gastrointestinal Malignancy Early Detection, Diagnosis, and Prevention Program at the University of Pittsburgh Medical Center, Pittsburgh. Given that, “I am not sure how to best highlight a communication approach that would not cause undue stress to the patient and our healthcare resources.”
Gaddam agreed that it’s tough to pinpoint or communicate straightforward risks or symptoms to the general public without potentially leading to unnecessary screening.
At a minimum, however, clinicians can share more general risk-mitigating strategies with their patients.
Communicating such strategies may be especially important for younger patients, given that the recent survey found almost 40% of younger adults believe there’s nothing they can do to change their risk for pancreatic cancer.
However, Cruz-Monserrate explained, adults of all ages can lower their risks through regular exercise, limited alcohol and tobacco use, and a healthy diet with less red meat or processed meat.
Ultimately, for clinicians, given how difficult it is now to identify pancreatic cancer early, we have to “follow their good clinical judgement when alarming features, such as weight loss or nuances of pancreatic pain arise, and then get good imaging,” Gaddam said.
Cruz-Monserrate, Brand, and Gaddam reported no relevant disclosures.
