The Study
Early-Life Mutagenesis and the Rise of Early-Onset Colorectal Cancer
This article is like someone saying, 'Maybe eating too much candy as a kid could make you sick when you're older.' But they didn't actually study any kids or measure candy or sickness. They just had an idea.
Analysis score
Maximum 0 for a editorial/opinion.
Where the score came from
Some bacteria in the gut during childhood might accidentally damage DNA in the colon, and those damaged cells can grow into cancer many years later.

DNA damage from certain bacteria in early childhood may lead to colorectal cancer that appears later in adulthood.
Exposure to certain bacteria that produce DNA-damaging substances in early childhood may lead to genetic changes in the colon that can eventually result in colorectal cancer many years later.
