Stomach (Gastric) Cancer
Cancer of the stomach, also called gastric cancer, is a malignant
tumor arising from the lining of the stomach. According to the
National Cancer Institute (NCI), the estimated numbers of new cases
and deaths from gastric cancer in the United States in 2005 were:
New cases: 21,860
Deaths: 11,550
The NCI also reports that gastric cancer now ranks 14th in incidence
among the major types of cancer malignancies in the US.
Stomach cancers are classified according to the type of tissue where
they originate. The most common type of stomach cancer is
adenocarcinoma, which starts in the glandular tissue of the stomach
and accounts for 90 to 95% of all stomach cancers. Other forms of
stomach cancer include lymphomas, which involve the lymphatic system,
and sarcomas, which involve the connective tissue (such as muscle,
fat, or blood vessels).
Stomach cancer can often be cured if it is found and treated at an
early stage. Unfortunately, the outlook is poor if the cancer is
already at an advanced stage when discovered.
What Causes Stomach Cancer?
The exact cause of stomach cancer is unknown, but a number of
conditions can increase the risk of the disease. These include:
Helicobacter pylori (H. pylori) infection of the stomach. H.
pylori is a bacterium that infects the lining of the stomach and
causes chronic inflammation and ulcers.

Chronic gastritis.
Pernicious anemia.
Some gastric polyps.
Family history of gastric cancer.
Smoking.
