The detection of early colon cancer has increased since the advent of screening colonoscopy. Endoscopic resection can be performed to cure early colon cancer with no metastasis. Therefore, we should correctly predict the possibility of metastasis before a trial of endoscopic resection. Metastasis may be assessed using chromoscopy with magnification, narrow band imaging, and endoscopic ultrasound, as well as with conventional imaging studies such as computed tomography (CT) and magnetic resonance imaging (MRI). Various endoscopic resection techniques, including endoscopic submucosal dissection, can be performed to resect early colon cancer. The histopathological evaluation of endoscopically resected early colon cancer can provide clinicians with further information about the risk of regional lymph node metastasis. The decision to perform additional surgery is based on the histopathological examination of the resected specimens.
