Endoscopic Diagnosis of Small and Minute Colorectal Cancers

  • Masahiro Igarashi

Abstract

Clearly, colorectal cancer lesions do not suddenly appear at a size of 10–20 mm in diameter. Instead, they arise from minute cancers (≤5 mm) that grow into small cancers (>5 to 10 mm). Clinically, the probability of detecting a minute cancer is low (1). Small lesions such as adenomas and hyperplastic polyps account for an overwhelmingly large proportion of those detected by endoscopy (2). Hence, it is difficult to find such cancers with ordinary observation.
