Stomach cancer statistics

Stomach cancer is the fifth most common cancer in the world, with 952,000 new cases diagnosed in 2012.

  • Stomach cancers are divided into cardia (the top part of the stomach, near the oesophagus) and non-cardia cancers, depending on where they first appear.
  • Stomach cancer is more common in older adults and is about twice as common in men than women.
  • The bacterium Helicobacter pylori is an important cause of stomach cancer, particularly non-cardia cancer. Epstein-Barr virus, which is carcinogenic to humans, has also been linked to stomach cancer in some studies.
  • Tobacco use is a cause of stomach cancer.

The Continuous Update Project Panel made the following judgements:

  • Consumption of alcoholic drinks and foods preserved by salting are probably causes of stomach cancer
  • Consumption of processed meat is probably a cause of non-cardia stomach cancer
  • Greater body fatness is probably a cause of cardia stomach cancer

Preventability estimates using the new findings from the Continuous Update Project show that about 15% of cases of stomach cancer in the US could be prevented by being a healthy weight, having a healthy diet and not drinking alcohol.

The countries with the top 20 highest incidence of stomach cancer in 2012 are given in the tables below.
