There is no "regular screening system" for stomach cancer in the United States,
The following tests will be performed as needed.
Early detection tests for stomach cancer
Things to consider when undergoing testing
Gastric endoscopy vs.
swallow test
Gastric endoscopy is recommended over barium X-ray examinations because it has a much higher cancer detection rate* and fewer missed diagnoses. Furthermore, barium X-ray examinations are rarely performed for screening purposes in the United States.
H. pylori test
While H. pylori testing is not a test that directly detects stomach cancer, the infection rate among Japanese people is high, and this is the biggest risk factor for stomach cancer. If an infection is present, treatment can lead to effective prevention of stomach cancer.
Insurance confirmation
In the United States, there is a high risk that stomach examinations will be entirely out-of-pocket expenses. Since this depends on your insurance, be sure to check beforehand.
The necessity of testing
In the United States, where regular stomach cancer screenings are not available, it is crucial to clearly communicate your specific symptoms, family history, and the fact that Japanese are at high risk of stomach cancer to healthcare professionals and get them to acknowledge that testing is necessary.
