Public Health Interventions for Gastric Cancer Control

Abstract

Despite its generally decreasing trend in incidence, gastric cancer remains the fifth-most common cancer worldwide. Gastric cancer has substantially declined over the past century, thanks to decreases in risk factors such as Helicobacter pylori infection, tobacco smoking, and salt-preserved food intake. These decreases have resulted from natural interventions and population-based intervention strategies. H pylori eradication for infected patients has potential as a prevention strategy for those at high risk, but warrants a longer follow-up period. The ongoing increase in obesity prevalence may cause an increase in cardia gastric cancer, especially in Western populations, and should be carefully monitored.
