    Abstract:
    The simple, quick and non-invasive application of the "Bi-Digital O-Ring Test Cancer Screening Method" for adenocarcinoma of the stomach originally described by Y. Omura, indicated 21 out of 196 randomly selected patients who visited our hospital (114 male and 82 female with an average age of 57.2 years) to have a cancer positive response regardless of their original chief complaint. In all these 21 patients we did imaging of the outline of the stomach and localized adenocarcinoma positive area with the "Bi-Digital O-Ring Test Imaging Method." 5 out of 21 patients were confirmed to have adenocarcinoma of the stomach by microscopic examination of biopsied stomach tissue following X-ray and gastroscopic examination. Of these 5 patients with the cancer, 3 had no chief complaint indicative of stomach problems. This study indicated that simple, quick and non-invasive cancer screening method using "Bi-Digital O-Ring Test" with microscopic slide of adenocarcinoma of stomach as reference control substance, can detect stomach cancer with much greater accuracy, without giving any physical discomfort to the patient and with minimum time and expense, compared with well established standard x-ray and gastroscopic examination methods. The effectiveness and relative accuracy of mass screening of patients for gastric cancers using "Bi-Digital O-Ring Test" was well established by this study.
