H. Pylori Exposure and Colorectal Cancer: The Evidence Grows

A risk-attribution modeling study based on estimates from 43 studies suggests that Helicobacter pylori exposure, long established as a cause of gastric cancer, may also contribute to colorectal cancer risk. The meta-analytic approach strengthens the epidemiological link between H. pylori infection and CRC, potentially expanding the cancer burden attributable to this bacterium. If confirmed in prospective interventional studies, H. pylori eradication strategies could have broader cancer-prevention implications beyond the stomach.
