RT Journal Article SR Electronic T1 Classification and Histological Characteristics of Colorectal Cancer JF American Society for Clinical Laboratory Science JO Clin Lab Sci FD American Society of Chemistry and Laboratory Science DO 10.29074/ascls.2022003206 A1 Dubansky, Brooke A1 Lewis, Sally A1 Telgenhoff, Dale YR 2024 UL http://hwmaint.clsjournal.ascls.org/content/early/2024/09/18/ascls.2022003206.abstract AB Classification and staging of recognized colorectal cancer subtypes are based on histological characteristics of the lesion and predictable changes in morphology. Adenocarcinoma arising from adenomatous polyps is the most common type of colorectal cancer. The histological progression from benign, non-neoplastic polyps to invasive neoplastic adenocarcinoma is, in many cases, correlated with specific molecular aberrations. This review describes the classification, histological characteristics, and progression of non-neoplastic, as well as benign and malignant neoplastic, colorectal lesions.
