Eliminating common bacterial infection significantly decreases gastric cancer risk

While it is well known within the medical community that there is a link between the bacteria Helicobacter pylori (H. pylori) and rates of gastric cancer—commonly referred to as stomach cancer—the rates and risk among Americans has been largely understudied. Now, after analyzing records of close to 400,000 patients, researchers in the Perelman School of Medicine at the University of Pennsylvania, have found that successfully eliminating H. pylori from one’s gastrointestinal tract led to a 75 percent reduction in risk of gastric cancer. Researchers also found that rates of gastric cancer after detection of H. pylori infection are higher among specific populations, suggesting that people who fall into these groups could benefit from more careful monitoring. The study is published in the journal Gastroenterology.
