A type of bacteria called Helicobacter pylori (H. pylori) is likely responsible for millions of stomach cancer cases globally. According to scientists from the International Agency for Research on Cancer, if current trends continue, around 15.6 million people born between 2008 and 2017 will be diagnosed with stomach cancer in their lifetime.
Research shows that H. pylori infection accounts for 76% of these cases. The bacteria infects the lining of the stomach and is thought to spread from person to person and via contaminated food and water. Most people with H. pylori do not experience symptoms, but it can cause indigestion, bloating, or nausea.
Early detection through blood tests, breath tests, or stool samples can help identify infected individuals. Scientists are calling for increased investment in preventing stomach cancer, particularly through “screen and treat” programs that target H. pylori infection.
In contrast, stomach cancer rates in the UK have been decreasing over the past decade, with a 26% drop since 2010. Experts say that while H. pylori is an important issue globally, other factors contribute more to cancer cases in the UK.
Reducing cancer risk can be achieved by quitting smoking, maintaining a healthy weight, limiting alcohol consumption, and eating a balanced diet. The study found that implementing screen-and-treat strategies for H. pylori could cut stomach cancer cases by up to 75% globally.
