A new global study suggests that younger generations may be ageing faster internally, potentially increasing their risk of cancer. Researchers analyzed data from over 160,000 people and found that younger individuals show more signs of biological wear and tear and inflammation, making their biological age exceed their actual age.
Biological Age vs. Chronological Age
Scientists believe this accelerated biological ageing could help explain why younger adults are being diagnosed with cancers traditionally associated with older age. Dr. Lochlan Fennell from the University of the Sunshine Coast noted, "The key gap now is trying to understand what's driving that lifestyle changes, the obesity, the microplastics. They're all things that could be conduits for that acceleration in ageing."
Personal Story: Kylie Swords
Kylie Swords, 37, was diagnosed with stage three bowel cancer last year after her GP dismissed her concerns. "I was 37. I had two really young kids. I was working full time. It was a huge shock, a huge surprise," she said. After treatment, she is now in remission and advises others: "Get a second opinion if you're not happy with the answers. You're the expert on your body. Nobody's too young for this stuff."
Implications for Cancer Detection
The future of cancer detection may involve measuring biological age to determine if more tests are needed, rather than relying solely on chronological age. Doctors emphasize that while there is no guaranteed way to reverse ageing, maintaining a healthy lifestyle is a good starting point.
