Experts have raised concerns about a growing number of bowel cancer cases among people under 50, with no clear explanation for the trend. Although the disease remains much more common in older adults, researchers highlight an average annual rise of 3.6% in England, making it one of the countries most affected. Poor diets and obesity are believed to play a role, with processed meats and low fibre intake among the potential risk factors.
A global study spanning 50 countries from 2007 to 2017 found increased cases in younger adults across 27 nations, including both wealthy and developing regions. This rise, described as a "global phenomenon" by Dr Hyuna Sung from the American Cancer Society, suggests that bowel cancer is no longer confined to high-income nations. Early detection remains crucial, and public awareness of symptoms such as persistent changes in bowel habits, blood in stools, and abdominal discomfort is vital.
Despite the uptick, bowel cancer in younger people is still relatively rare. In the UK, only about one in 20 bowel cancer diagnoses occur in under-50s, with 2,600 out of 44,100 annual cases affecting those aged 25-49. Experts suggest improved screening and earlier detection may partly explain the rise, alongside lifestyle factors such as alcohol use and smoking.
The late Dame Deborah James, known for her advocacy and openness about living with bowel cancer, encouraged people to pay attention to their bowel health. Her message remains a powerful reminder to seek medical advice if symptoms arise, helping to catch the disease early when treatment is most effective.
