Colorectal cancer (commonly called bowel cancer) is indeed increasing at an alarming rate among young people.
According to multiple studies including those published in Nature Medicine and reported by major outlets like The Guardian and NBC News:
Rates of early-onset colorectal cancer (EOCRC)—especially in those under 50—are doubling roughly every decade.
A recent international study of 981 tumor samples from 11 countries found a bacterial toxin called colibactin, made by certain E. coli strains, was significantly more common in younger patients' tumors (under 40 years old) than in older adults.
Colibactin damages DNA and may silently initiate cancer development years before diagnosis—potentially beginning in childhood.
While traditional risk factors (obesity, diet, sedentary life) still matter, this research shifts focus to gut microbiome health in early life.
Researchers are now exploring how to intervene—via probiotics, early-life nutrition, or gut-friendly interventions—to reduce long-term cancer risk.
Although colibactin’s presence is not confirmed as the sole cause, it’s a crucial new lead in understanding this generational shift.
