Brief Summary:
The purpose of this study is to conduct a study on genetic pathology, obtaining of pure cancer tissues is mandatory. Although the endoscopy with biopsy has been a gold standard for diagnosing gastric cancer, percentage of cancer cells in biopsy samples is usually 30% or less. Recently, confocal laser endomicroscopy has been introduced for real-time histopathologic diagnosis in various cancers. The investigators aim to evaluate that biopsy using probe-based confocal laser endomicroscopy will increase the percentage of cancer cells in biopsy samples.

Arm Intervention/treatment
Experimental: Probe-based confocal laser endomicroscopy Procedure: Probe-based confocal laser endomicroscopy
In this arm1, an investigator observes a cancerous lesion using white light endoscopy. In addition, contrast dye for confocal laser endomicorscopy (fluorescein sodium 0.1mL/kg) is administered. Then, the cancerous lesion is observed using probe-based confocal laser endomicroscopy. The biopsy would be done 5 times at the most suspcious parts of the cancerous lesion.
Active Comparator: White light endoscopy Procedure: White light endoscopy
In this arm2, an invesigator observes a cancerous lesion using white light endoscopy. The biopsy would be done 5 times at the most suspicious parts of the cancerous lesion.
