A Hidden Warning Sign Discovered in The Gut May Increase Cancer Risk

As we get older, chemical marks on our DNA slowly shift. Now, a study reveals this 'drift' in gut stem cells is fueled by inflammation and disrupted cell signaling, and it may help explain why our risk of colorectal cancer rises with age.
The international team of researchers has called this process Aging and Colon Cancer-Associated (ACCA) drift, and it involves shifts in DNA methylation that can 'switch' genes on or off without altering the DNA – called epigenetic changes.
In this case, the drift leads to the gradual si
