Bowel cancer rates in people under 50 are rising worldwide, prompting researchers to study century-old tumor samples for causes.
Bowel cancer rates in people under 50 are rising globally, with a 51% increase since the 1990s, prompting scientists to study a unique archive of tens of thousands of preserved tumor samples from St Mark’s Hospital in the UK.
Researchers, including Dr. Kevin Monahan and Prof. Trevor Graham, are using modern molecular techniques to analyze DNA damage patterns in these century-old samples, seeking links to environmental or biological factors like harmful gut bacteria, ultra-processed foods, pollution, or antibiotics.
The goal is to uncover causes behind the early onset of the disease and improve early detection and prevention strategies.
