Based on 2020-2022 data, the countries with the highest rates of stomach (gastric) cancer are primarily located in Eastern Asia, with Mongolia, Japan, and the Republic of Korea reporting the highest incidence rates. China, Japan, and India account for the highest number of deaths. Key risk factors include H. pylori infection, smoking, and dietary habits.

Key Findings on Stomach Cancer Rates:
Highest Incidence (Cases): Mongolia (32.5 per 100,000), Japan (31.6 per 100,000), and South Korea (27.9 per 100,000) have the highest age-standardized incidence rates.

Highest Mortality (Deaths): Mongolia, Tajikistan, and China report the highest mortality rates.

Regional Concentration: Roughly 60% of all global gastric cancer cases occur in Eastern Asia, with China alone accounting for over 43%.

Male Dominance: Incidence is higher in males, with rates exceeding 30 per 100,000 in parts of Eastern Asia.

Secondary Hotspots: High rates are also found in parts of Central/South America and Eastern Europe.

Due to the high prevalence, Japan and Korea have implemented national screening programs, which have significantly increased 5-year survival rates compared to other countries.
