Stomach cancer - Definition

March 2017


Definition


Stomach cancer exists in several different forms, but the most common develops in the glandular mucosa of the stomach. Cells that are initially healthy will slowly begin to transform and to develop into a mass called adenocarcinoma. It often appears, after the age of 50, in the form of abdominal pain, vomiting, bleeding, and the appearance of a mass in the abdomen. The lack of specific symptoms often leads to a late diagnosis. An endoscopy enables the detection of the tumor and its characterization. The treatment is often surgical, where part of the stomach is removed (gastrectomy) and an anastomosis (operation linking two lines) is performed.
