A common bacterium, Helicobacter pylori (H. pylori), is linked to millions of projected stomach cancer cases globally.
Scientists estimate 15.6 million people born between 2008 and 2017 will be diagnosed with stomach cancer in their lifetime, with 76 per cent directly linked to H. pylori infection.
The vast majority of these projected cases, 10.6 million, are expected in Asia, followed by the Americas, Africa, and Europe.
Experts from the International Agency for Research on Cancer (IARC) are calling for greater investment in prevention, particularly through population-wide “screen and treat” programmes for H. pylori, which could cut cases by up to 75 per cent.
Cancer Research UK notes that stomach cancer rates are falling in the UK, where H. pylori infection is less common, and other lifestyle factors are more significant for cancer prevention.
