- The World Cancer Research Fund analyzed data from 12 different cancer types across England, the United States, and the Netherlands over a 20-year period, The Guardian reported.

Younger generations face a higher incidence of certain cancers than previous generations did at the same age, according to a report from the World Cancer Research Fund cited by The Guardian. The finding reverses decades of public health expectations that successive generations would live longer and healthier lives.
Cancer Rates Rise Among Adults Under 50 in England, the US, and the Netherlands
The World Cancer Research Fund analyzed data from 12 different cancer types across England, the United States, and the Netherlands over a 20-year period, The Guardian reported. Among women under 50 in England, breast, bowel, uterine, kidney, liver, pancreatic, and stomach cancers have all increased. For men under 50 in England, rates climbed for bowel, kidney, liver, pancreatic, and prostate cancers. The data shows younger birth cohorts experience an elevated risk compared to older generations at an equivalent point in life.
Dietary Changes, Sedentary Lifestyles, and Environmental Toxins Under Investigation
Scientists are investigating what changed between the 1950s and the 1990s to trigger the uptick in early-onset cancer, according to The Guardian. Researchers are examining shifts in diet, including the rise of ultra-processed foods, fast foods, and sugary drinks, alongside increasingly sedentary populations. These shifts correlate with rising obesity levels, which have more than doubled among adults and quadrupled among adolescents globally since 1990. Data from 2024 shows that roughly 66% of adults in England are overweight or living with obesity. However, researchers note that excess body weight does not fully account for trends like rising pre-menopausal breast cancer rates, prompting investigation into sustained exposure to environmental toxins such as air and water pollution, chemicals, and plastics.
Anti-Smoking Campaigns Reduce Lung Cancer Rates in Young People
Not all cancer metrics among younger populations are worsening, as anti-smoking campaigns have successfully driven down lung cancer rates in young people through widespread public awareness, The Guardian reported. Researchers emphasize that individual behavior accounts for only about 40% of cancers at a population level, while the remaining 60% stems from aging, genetics, infections, environmental factors, and chance. Ongoing scientific investment aims to clarify these generational risk factors, though the primary drivers of early-onset cancer remain under active investigation.
