A definitive way of diagnosis of most types of gastrointestinal cancers biopsy is preferred. If biopsy is not possible, the doctor may suggest other tests that may help to make diagnosis. Imaging tests may be used to find whether cancer has spread. Early diagnosis of cancer is very difficult because mostly patients are asymptomatic during the early stages. Esophagogastroduodenoscopy is the preferred diagnostic method for evaluation of patients with whom stomach cancer is suspected. Radiographic study provides preliminary information that help the physician to determine if a gastric lesion is present and whether the lesion has benign or malignant features.
