A group of scientists have found that the health of colon is decided by the bacteria present in our gut.
Gut microbiome, a collection of all bacteria, outnumbers all body cells by 10 to one. It is present in the gut of the human beings.
The researchers concluded the findings following analysis of the process by which the gut microbiome determines risk of colon cancer in any individual.
For the study, the researchers involved 90 participants-30 people with precancerous intestinal polyps, advanced colon cancer and healthy people each-and collected their stool samples. They tried to find out the composition of their gut microbiomes by testing the stool samples. They also commenced a test to find out for additional factors, like age and race, leading to colon cancer or precancerous polyps.
Following analysis of the gut microbiomes and BMI, the researchers said a 4.5-fold has improved prediction of precancerous polyps. They say the test was more accurate than the fecal occult blood analysis.
Patrick D. Schloss, PhD, said, “Our data show that gut micro biome analysis has the potential to be a new tool to non-invasively screen for colorectal cancer.”
“We don’t think that this would ever replace other colorectal cancer screening approaches, rather we see it as complementary,” said Schloss, an associate professor in the Department of Microbiology and Immunology at the University of Michigan.
According to a recent report, an estimated 137,000 Americans, i.e. 8.2 percent, will be diagnosed with colorectal cancer by the year-end.
If the statistics of the American Cancer Society is considered, one in 20 individuals will develop colorectal cancer. Men are at a greater risk than women.
The findings of the study were published in the journal Cancer Prevention Research.
