Gastric cancer is one of the tumors with higher worldwide mortality. Although the incidence rate has been declining, it is still a major public health problem still. Epidemiological information and knowledge about this cancer is abundant. This is an up to date review about commonly accepted risk factors: Helicobacter pylori infection, diet, genetic predisposition and socioeconomic status. We also stress the new questions and challenges that recent discoveries about this pathology entail. The ways to tackle this cancer are discussed using X rays and biological markers such as serum pepsinogens in high risk groups or populations.
