WCRF warns: Seven types of cancer have become more common in people under 50

The incidence of several types of cancer among people under 50 has risen significantly in England, the United States and the Netherlands, according to an analysis by the World Cancer Research Fund (WCRF). Researchers warn that these forms of cancer, although still rare among younger people, are developing faster than in other age groups.

In England, the largest increase was recorded for prostate cancer, from one case per 100,000 people in 2001 to 3.6 cases in 2023. The incidence of colorectal cancer rose from 3.9 to 8.4 cases per 100,000, while cases of cervical and kidney cancer doubled. Breast, pancreatic and liver cancers also increased.

In the US, kidney cancer more than doubled after 2000, while colorectal, uterine and pancreatic cancers increased by more than 50%. In the Netherlands, increases were observed in colorectal, kidney, liver and cervical cancers.

Specialists are examining links with obesity, unhealthy diets, sedentary lifestyles, alcohol, smoking and pollution. Approximately 40% of cancer cases are associated with modifiable factors. At the same time, earlier diagnosis may partly explain the trend. Lung cancer is the exception, with its incidence declining in all three countries as smoking rates fell.
