An imaging technology reveals that bacterial biofilms are associated with colon cancer, researchers report. . . ."This is the first time that biofilms have been shown to be associated with colon cancer, to our knowledge," . . . In healthy people, the colon is covered in a mucus layer (mucosa) that helps keep bacteria away from the colon's "skin," or epithelia. Remarkably, the team found that colon cancer patients who have tumor-associated biofilms also have biofilms on tumor-free areas of the nearby mucosa.
