How the presence of bacteria from the mouth in the gut could help detect colorectal cancer

Researchers have identified a potential new method for detecting colorectal cancer by analyzing the presence of oral bacteria in the human gut. The study suggests that specific bacteria originating in the mouth leave distinct biological markers within the intestines of individuals affected by digestive tumors. This discovery is part of an ongoing effort to develop less invasive diagnostic tools for identifying colorectal cancer. By leveraging the connection between the oral microbiota and the gut, scientists aim to improve early detection capabilities for these malignancies.
