England's Under-50 Prostate Cancer Rate Has More Than Tripled Since 2001, World Cancer Research Fund Analysis Finds

Since the Nature Medicine study of younger colorectal tumors landed this week, more data has stacked up showing that cancer in under-50s is not just a bowel problem.

The World Cancer Research Fund (WCRF) analyzed NHS England Cancer Registry figures and found rising rates of seven cancer types in people under 50 between 2001 and 2023: prostate, colorectal, kidney, uterine, liver, pancreas and breast.

Prostate leads the rise in England

Prostate cancer shows the steepest climb. Cases among men under 50 went from about one per 100,000 in 2001 to nearly four per 100,000 in 2023. That is more than a tripling.

Bowel cancer cases more than doubled over the same period, from 1,289 to 2,989. Kidney cancer rose from 510 to 1,065 cases. Uterine cancer among women went from 335 to 698.

The WCRF also flagged increases in rarer cancers, which could receive less funding and less research focus. It called the pancreatic cancer rise "troubling given the low survival rate."

"These figures should make us pause and think because this current trajectory is concerning," said Giota Mitrou, the charity's executive director of research and policy. "Behind every figure is a person facing cancer earlier than they, their family and often their doctor would expect."

The charity was careful on scale. Cancer remains far more common in older adults. These are rising rates off a low base.

The U.S. numbers point the same direction

The American Cancer Society reports that colorectal cancer diagnoses among Americans under 50 rose 2.9% per year from 2013 through 2022. Its 2026 report names colorectal cancer the leading cause of cancer death in that age group.

The National Cancer Institute's 2025 report found that 14 cancer types increased in at least one under-50 age group between 2010 and 2019. The NCI also reported that the average age at colorectal cancer diagnosis in the U.S. has dropped from roughly 72 to 67.

Symptoms worth a doctor's visit include persistent abdominal pain, unexplained changes in bowel habits, rectal bleeding and iron deficiency anemia. These often have harmless causes, but persistent ones should be checked.

A new angle: biological age

A study covered by The Epoch Times looked at the gap between chronological age and biological age. That is a measure of inflammation, metabolic strain, and wear on organs and the immune system.

In a UK sample, people with the largest gap had a 15% higher risk of cancer before age 55. The effect was strongest for lung, gastrointestinal and uterine cancers. A smaller U.S. group of 10,000 participants showed an even larger biological-age gap between people born in the 1990s and those born in the late 1960s.

Organ-level results were sharper. An older-looking immune system carried a 1.89-fold higher relative risk of lung cancer before 55. Older-appearing fat tissue carried a 60% higher relative risk of colorectal cancer before 55.

Elissa Epel, a University of California, San Francisco psychiatry professor who was not part of the study, said biological age can be read as a marker of cumulative exposures: "stressors, toxins, processed food and other pro-aging factors." Ludger Goeminne, a Harvard researcher also outside the study, noted that organs age at different rates in the same person.

The study shows an association. It does not establish what drives the gap.

Iowa fights over the water

The causation question has turned political in Iowa, where Fox News medical analyst Dr. Marc Siegel reports the cancer rate runs 10% above the national average. Corn and soybean production, plus hog operations, send nitrogen runoff into rivers used for drinking water.

The EPA does not list nitrates as carcinogens. Siegel notes they can convert in the body into probable carcinogens through a process called nitrosation.

Tony Lyons, president of MAHA Action, told Siegel that numerous studies link nitrate-contaminated water to cancer. He added that not every Iowa politician is equally committed to cutting chemical exposure. Republican gubernatorial candidate Zach Lahn said, "Any discussion that does not include water quality and the nitrate load when we're talking about cancer isn't a serious discussion."

The state's own research points elsewhere. University of Iowa work, funded by the state, still finds that most, though not all, of Iowa's above-normal rates for several cancers are explained by demographic and behavioral factors such as smoking and binge drinking.

Unresolved causes

Nobody in this body of research claims a single culprit. The WCRF lists diet, physical activity, body weight, alcohol, smoking, air pollution, chemicals, plastics, water pollutants and changes in how cancers get diagnosed as candidates. Researchers examining the gut microbiome are testing whether toxins from specific bacterial strains contribute to colorectal cancer. Inherited genetics alone do not explain a rise this fast.

That last point matters for the diagnosis factor. More screening and awareness can raise recorded cases without raising true incidence, and the WCRF lists it alongside the lifestyle and environmental suspects. Rising kidney and prostate numbers are the kind of finding where researchers will want to separate more detection from more disease.

It is unclear which of these factors accounts for the share of Iowa's excess that University of Iowa researchers say remains unexplained, and whether the same unexplained share exists in England's under-50 numbers. The WCRF has called for the rise to be treated as a research and prevention priority, but it has not announced a specific funded study.
