Rates of bowel cancer among younger adults are increasing globally, with no clear reason why, experts warn. While the disease still affects older people more often, the rise in many countries among under-50s is concerning.
According to a study published in Lancet Oncology, England has seen a 3.6% increase per year in bowel cancer cases among younger adults. Researchers attribute this rise to poor diet and obesity as potential risk factors.
Eating too much processed meat and not enough fibre can increase the risk of bowel cancer. The study found that many countries with rising rates were also richer nations, but some developing countries were affected as well.
“The increase in early-onset colorectal cancer is a global phenomenon,” said Dr Hyuna Sung, one of the authors.
Experts warn that people need to be aware of the early signs and symptoms, such as blood in stool or persistent changes in bowel habits. Despite low rates among younger adults overall, more research is needed to understand this trend.
In the UK, about 2,600 new cases of bowel cancer each year are diagnosed in those under 50. Experts suggest that factors like diet, obesity, and improved detection may contribute to this rise.
