 Biopsy is necessary for the diagnosis of cancer. However, if multiple biopsies were taken from a tiny lesion(≦5mm), the lesion might disintegrate and the diagnose of lateral extension would become difficult. Biopsy has a potential to cause the cancer to appear to disappear, even if only one biopsy is taken. Therefore, the selection of biopsy site and size is important to prevent apparent disappearance after biopsy. Therefore, only one biopsy should be taken from the edge of the lesion by small biopsy forceps. The optimum area for taking a biopsy from a tiny lesion is very small. Therefore, the endoscopists have to have the skill to take a biopsy from an adequate site. If the biopsy is taken from an inappropriate site, it would be difficult to make a correct diagnosis and decision. A transparent hood makes it easy to take a precise biopsy. Therefore, re-examination with a transparent hood should be considered if the approach to the tiny lesion is difficult.
