The Claim
Colibactin-induced mutational signatures SBS88 and ID18 are enriched in early clonal mutations of colorectal cancer, indicating that exposure to colibactin occurs early in life and contributes to the initial mutational burden before tumor development.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
DNA damage caused by the bacterial toxin colibactin is found in the earliest genetic changes in colorectal cancer, suggesting that exposure to this toxin happens early in life and helps create the initial mutations that lead to cancer.

What the research says
1 studyStudy: Geographic and age variations in mutational processes in colorectal cancer
This study found that a harmful bacterial toxin called colibactin leaves a unique fingerprint in the DNA of early-onset colon cancers, meaning people were likely exposed to it when they were young—before they even got cancer. This helps explain why more young people are getting colon cancer today.
