Core Tip

Core tip: Colorectal cancers (CRC) arise from 3 pathways: adenoma to carcinoma; “Lynch syndrome”; and serrated. There are 3 types of serrated lesions namely: Hyperplastic Polyps, Sessile Serrated Adenomas/Polyps and Traditional Serrated Adenomas, the latter two are associated with CRC. A careful examination of borders, submucosal injection with dye and ensuring that a rim of normal tissue is removed is paramount.
