Stomach cancer is the fourth most commonly occurring cancer in men and the seventh most commonly occurring cancer in women. There were over 1 million new cases in 2018. The top 20 countries with the highest rates of stomach cancer in 2018 are given in the tables below.

The Continuous Update Project Panel judged there is strong evidence that greater body fatness and consumption of alcoholic drinks and foods preserved by salting are causes of stomach cancer. There is some evidence that consumption of processed meat and grilled or barbecued meat and fish, and low consumption of fruit, might increase the risk of stomach cancer. There is some evidence that consumption of citrus fruit might decrease the risk of stomach cancer. Read about all the evidence in our Third Expert Report.

Age-standardised rates are used in the tables. This is a summary measure of the rate of disease that a population would have if it had a standard age structure. Standardisation is necessary when comparing populations that differ with respect to age because age has a powerful influence on the risk of dying from cancer.
