 Animal experiments and molecular biology as well as epidemiological studies have produced results supporting a causal relationship between Helicobacter pylori (Hp) infection and the risk of gastric cancer. Hp may elevate the risk 20 to 40 times. Eradication of Hp in adulthood may reduce the risk for those infected with Hp by one third, which is still about ten times higher than those who have never suffered Hp infection. Most Hp infection occurs in childhood. A strategy eradicating Hp in those who have direct contact with children to helpprotect the children from Hp infection should be considered as an effective prevention against gastric cancer.
