Screening is a way to evaluate people without symptoms to determine if they are at risk for cancer or have already developed cancer.
At this time, there are no official screening guidelines for stomach cancer. Testing is only recommended for people who are experiencing symptoms suggestive of this cancer. People who smoke or drink large amounts of alcohol, however, should be advised to stop, and informed of their greatly increased risk of stomach cancer and other serious diseases.
However, endoscopic screening or upper gastrointestinal imaging is standard for those >50 years old in countries of high incidence (eg, Japan).
