There are several causes of stomach cancer. To name a few are previous exposure to radiation, bacterial infection caused by Helicobacter pylori, pernicious anemia, stomach surgery, as well as genetic factors that cause predisposition to the disease. Helicobacter Pylori infection is rarely associated with stomach cancer at the junction of the stomach and the esophagus. If you got this disease from any other medication or treatment  then you can also file the Stomach Cancer lawsuit.

Stomach cancer is a very serious condition. Symptoms usually arise later due to the large capacity of the stomach and often the tumor is not curable at the time of diagnosis. The mortality rate for stomach cancer patients is high. The high incidence of stomach cancer in the Far East is likely due to high rates of Helicobacter Pylori infection and certain dietary factors. 

It is not known why stomach cancer incidences are declining in the United States. One possible explanation is the low incidence of Helicobacter Pylori infection, a known carcinogen that can cause stomach cancer. 

The American Cancer Society recommends that stomach cancer be diagnosed by endoscopic surgery. This is because the rate of stomach cancer in the United States is very low. If warning signs such as bleeding or diarrhea are detected early, a diagnosis can sometimes be made. A lot of people over 50 have their stool tested for blood every year.
