Study: Cancer Rising Sharply in Patients Under 50

Is the rise in cancer among young adults a genuine epidemic of disease or an epidemic of overtesting and overdiagnosis?

The Facts

  • Analysis released by the World Cancer Research Fund found significant increases in early onset cancers for seven cancer types in England, five in the United States and four in the Netherlands, based on English, U.S. and Dutch data.
  • In England, prostate cancer diagnoses in men under 50 reportedly rose from 158 cases in 2001, or one per 100,000, to 640 cases in 2023, or 3.6 per 100,000, while early-onset bowel, kidney and uterine cancer diagnoses more than doubled.
  • Breast cancer rates among women under 50 in England climbed from 42 per 100,000 in 2001 to 47.5 per 100,000 in 2023. Lung cancer rates in the under 50s fell in all three countries studied, reflecting declines in smoking.

The Spin


Narrative A

Something real is happening to younger bodies, and brushing it off as better scanning is reckless. Obesity, ultraprocessed diets, alcohol, pollutants and a disrupted gut microbiome have stacked risk onto generations from childhood onward, and tumors in young patients look biologically different. Deaths are climbing too, so waiting for perfect proof means losing people in their prime.

Narrative B

An epidemic of testing is being mistaken for an epidemic of disease. More imaging, more scopes, more checks and lower thresholds for calling something cancer will always produce more diagnoses, yet deaths from most of these cancers have stayed flat or fallen. Hunting for mysterious new exposures drains money and attention while overdiagnosis runs the risk of turning healthy young adults into lifelong patients.
