Screening tests check for diseases in people who don’t have symptoms. Mass screening for stomach cancer is not done in the United States. That’s because the cancer is so rare in the U.S. Most Americans with this type of cancer receive a diagnosis only when they have developed symptoms of the disease.
Mass screening of stomach cancer is available in Japan. There, doctors diagnose the disease about 5 times more often than in the United States.
If you have a family history of stomach cancer or health problems that are associated with stomach cancer, your doctor may want you to have regular health exams to be sure there are no problems.
