Gastric Cancer

What is gastric cancer?

  • Cancer cells form in the lining of the stomach.

  • Almost all gastric cancers are adenocarcinomas :cancers that begin in cells that make and release mucus and other fluids:. Other types of gastric cancer are gastrointestinal carcinoid tumors, gastrointestinal stromal tumors, and lymphomas.

  • Infection with bacteria called H. pylori is a common cause of gastric cancer.

  • It is only found in advanced stages due to no signs or symptoms

  • In the early stages of gastric cancer, the following symptoms may occur:

Indigestion and stomach discomfort.

A bloated feeling after eating.

Loss of appetite.


  • In more advanced stages of gastric cancer, the following signs and symptoms may occur:

  • Upper endoscopy: A thin, lighted tube is inserted through the mouth to look for abnormal areas in the esophagus, stomach, and first part of the small intestine.
  • Serum pepsinogen levels: A test that measures the levels of pepsinogen in the blood. Low levels of pepsinogen are a sign of chronic gastric atrophy which may lead to stomach cancer.
  • Barium -meal photofluorography: A series of x-rays of the esophagus and stomach. The patient drinks a liquid that contains barium, a silver-white metallic compound, which coats the esophagus and stomach as it is swallowed. Photographs are taken of the x-ray images. The photographs are processed to make the organs easier to see and then made into a film. This makes it possible to see the motion of the organs while exposing the patient to less radiation.
