Young People’s Gut Bacteria May Be Driving Colorectal Cancer Risk

June 5, 2024 – Genetics and diet have been among the top theories for what may be fueling the troubling rise of colorectal cancer in young adults. Now, an early look at genetic data from people with the disease further suggests that the cause is linked to what is happening in the gut.

The researchers found signs that a high-fat, low-fiber diet may increase inflammation in the gut that prevents it from naturally suppressing tumors. The cells of young people with colorectal cancer also appeared to have aged more quickly – by 15 years on average – than a person’s actual age. That’s unusual, because older people with colorectal cancer don’t have the same boost in cellular aging.
