Colon screening examinations have been shown to discover neoplastic lesions at an early stage. Even the most careful studies by colonoscopy and by computed tomographic colonography (CTC) can overlook tumors with a diameter greater than 5 mm. Advances in technology have continually improved the ability to find polyps, which will lead to a real decrease in colorectal cancer incidence.
结肠镜检查已被证明能在早期发现肿瘤性病变。即使是通过结肠镜检查和计算机断层结肠成像（CTC）进行的最仔细的研究，也可能会遗漏直径大于5毫米的肿瘤。技术的进步不断提高了发现息肉的能力，这将导致结直肠癌发病率的真正下降。
