Why are more people under 50 getting cancer?

Reference:
Cancer remains predominantly a disease of older adults, but a World Cancer Research Fund analysis shows significant increases in several early-onset cancers (diagnosed before age 50) in England, the US and the Netherlands. In England (2001–2023 rates among under-50s):

Liver and pancreatic cancers also increased (smaller absolute changes).

Prostate cancer: rose from 1 to 3.6 cases per 100,000 (roughly quadrupled; absolute cases from 158 to 640).

Bowel cancer: rose from 3.9 to 8.4 cases per 100,000 (more than doubled).

Kidney cancer: rose from 1.5 to 3 cases per 100,000 (doubled).

Uterine cancer: rose from 1.8 to 3.9 cases per 100,000 (more than doubled).

Breast cancer: rose more modestly from 42 to 47.5 cases per 100,000.
