The incidence of gastric cancer in Spain as well as globally is progressively declining. However it is the second leading cancer worldwide. The most frequent gastric cancer type is adenocarcinoma that is classified in 2 different types: intestinal and diffuse. Several environmental factors have been identified to play an important role in gastric carcinogenesis, including Helicobacter pylori infection, smoking and different dietetic factors. Gastric cancer is usually asymptomatic and when symptoms appear it usually reflects an advanced disease and a poorer prognosis. Endoscopy with biopsy sampling is considered the standard in gastric cancer diagnosis, and need to be complemented with additional imaging techniques such as endoscopic ultrasound or CT scan for tumor staging. The gold standard for gastric cancer treatment is surgery when the tumor is resectable although it is not known what is the better surgical technique. There are other histological types in gastric cancer that include lymphoma, carcinoid tumors and gastrointestinal stromal tumors (GIST)
