The Link Between Gut Microbiome Changes and Colorectal Cancer Risk.
A study by Mass General Brigham has found a link between certain types of gut bacteria and the development of precancerous colon polyps. The study analyzed the gut microbial signature of people without colon polyps, with tubular adenomas, or with sessile serrated adenomas and found that bacterial signatures clustered into three groups based on the type and presence of polyps in the colon. The hope is that by changing specific aspects of the diet or the microbiome, interventions to prevent polyp formation or alter their growth patterns may ultimately prevent colorectal cancer.
