title: [Epidemiological characteristics of gastric cancer].
abstract: BACKGROUND
  Gastric cancer was the third most common cancer worldwide in 2000, accounting for approximately 876 000 new cases or 9% of the global cancer burden.
  As a result of changes in diet, the incidence of gastric cancer has decreased in most countries. Nowdays, consumption of fresh vegetables and fruits is increasing in regard to canned food. In addition to unhealthy diet, the main risk factors for gastric cancer are H. pylori infection, alcohol consumption, smoking, gastritis, stomach ulcer, gastrectomy, stomach polyposis, positive family history for gastric cancer, pernicious anemia and blood type A. Diet rich in vegetables and fruits, and reduced salt intake can prevent 65-75% of gastric cancer cases among nonsmokers. Prevention of Helicobacter pylori infection can also reduce the incidence of this malignant disease.
