Increased Occurrence of Colorectal Cancer Among Younger Age Groups: Possible Explanations Revealed by Scientific Investigations
Lemme spill the beans on a gut bacteria that's causing quite a stir. A study published this week in Nature reveals that certain strains of Escherichia coli produce a mutagenic toxin called colibactin, which could be triggering early onset colorectal cancer.
Researchers led by the University of California, San Diego made this discovery. They found a link between exposure to colibactin and colorectal cancers more likely to occur in young adults. This could help explain the mysterious rise in early onset colorectal cancer rates we've been seeing lately, although more research is needed to confirm a causative connection.
Colorectal cancer is the fourth most common cancer, with around 150,000 Americans diagnosed each year. It's also the second leading cause of cancer-related deaths, killing about 50,000 annually. The incidence and death rate of colorectal cancer have been steadily declining over time, but not equally for everyone. The rates of colorectal cancer have been increasing in young and middle-aged adults. According to the American Cancer Society, rates of colorectal cancer have increased by 2.4% per year between 2012 and 2021 among people under 50.
While scientists aren't entirely sure why these cancers are becoming more common in younger Americans, some research has pointed fingers at processed foods, higher obesity rates, and other lifestyle factors. But this new study adds another potential culprit: colibactin.
The study's researchers weren't specifically searching for this answer; they were more interested in understanding why some parts of the world have higher reported rates of colorectal cancer than others. To do this, they analyzed the genetic signature of colorectal cancers taken from nearly 1,000 people across the world. They found that colibactin-related mutations were three times more commonly found in the early onset cancers they studied compared to the late onset cancers. They also found evidence that these colibactin-related mutations often appear in the first ten years of life, suggesting they play a crucial role in fueling these cancers.
In a statement, senior study author Ludmil Alexandrov, a researcher specializing in cancer genomics at UC San Diego, said, "These mutation patterns are a kind of historical record in the genome, and they point to early-life exposure to colibactin as a driving force behind early-onset disease." The researchers note that colibactin could be just one piece of a larger puzzle. They suggest that other environmental factors, such as diet or antibiotic use, could be encouraging the growth of colibactin-producing E. coli bacteria in the gut in places like the U.S.
The research team's findings could potentially lead to interventions that could slow or reverse the rise in early onset colorectal cancer. They're exploring whether probiotics might be able to eliminate these more harmful E. coli strains, and they're trying to develop early detection tests that can screen for colibactin-related mutations. However, this work is contingent on further funding, and the researchers are concerned about aggressive funding cuts from the National Institutes of Health under President Trump.
