3 articles · Updated · BuzzFeed · May 16
1 in 5 colorectal cancer diagnoses now occur in people under 55, marking a shift in a disease long linked mainly to older adults.
Doctors say no single cause explains the rise, but point to diets higher in ultra-processed foods and sugar and lower in fiber.
Higher obesity and metabolic dysfunction rates, along with alcohol use and prolonged sedentary time, are also cited as likely contributors.
Researchers are also examining early-life antibiotic exposure, gut microbiome changes, and environmental factors such as microplastics, though that evidence is still evolving.
Why is colorectal cancer surging in young adults with none of the traditional risk factors?
With microplastics now found in tumors, how might these particles be triggering cancer in people under 50?
Can we reverse gut damage from past antibiotic use to lower the rising colorectal cancer risk?
