It is thought that the development of cancer of the stomach follows a series of stages in which the lining becomes increasingly abnormal. Early detection of precursors of gastric cancer likely enable less invasive treatment. The assessment of gastric mucosa using the endoscope is used to detect cancers and these precursor lesions. Narrow band imaging uses filtered light already built into modern endoscopoes to identify the early changes in the gastric lining. The investigators' hypothesis is that narrow band imaging improves detection of precursor lesions and is a method amenable to international standardization. The investigators will conduct a prospective trial in which standard random biopsy, white light guided biopsy, and narrow band imaging guided biopsy will be performed for each patient. The yield of the different methods for gastric cancer precursors will thus be compared.
