THURSDAY, July 10, 2025 (HealthDay News) — Among young people born in 2008 to 2017, 15.6 million lifetime gastric cancer cases are expected globally, with more than three-quarters attributable to Helicobacter pylori<\/em>, according to a study published online July 7 in Nature Medicine<\/em>.<\/p>\n Jin Young Park, Ph.D., from the International Agency for Research on Cancer in France, and colleagues projected the future burden of gastric cancer, including that attributable to H. pylori<\/em>, among a cohort of young people born in 2008 to 2017. In the absence of intervention, expected gastric cancer cases were quantified in 185 countries by combining national age-specific incidence rates and cohort-specific mortality rates.<\/p>\n The researchers found that within these birth cohorts, 15.6 million lifetime gastric cancer cases are expected globally, of which 76 percent will be attributable to H. pylori<\/em>. Of the cases, two-thirds will be concentrated in Asia, followed by the Americas and Africa. Overall, 58 and 42 percent of cases are expected in traditionally high-incidence areas for gastric cancer and in lower-incidence areas, respectively, owing to demographic changes, especially in sub-Saharan Africa, where the future burden may be sixfold higher than estimated in 2022.<\/p>\n “Our future estimates highlight an increasing burden of gastric cancer in areas traditionally considered to have low incidence, including Africa, and are of immediate relevance to public health decision-makers seeking to recalibrate prevention strategies based on local cancer profiles,” the authors write.<\/p>\n
