[Comment] Take a pill for no more polyps: is it that simple?

Colonoscopy is regarded as the gold standard for detection of colorectal cancer and its precursors, colorectal adenomas and sessile serrated lesions. This procedure should be able to prevent colorectal cancer by detecting and removing those precursor lesions. After adenoma or sessile serrated lesion resection, individuals are considered to be at high risk of developing metachronous lesions and colorectal cancer, and are therefore advised to undergo surveillance colonoscopy. Despite these preventive measures, post-colonoscopy colorectal cancers (PCCRCs) occur at a frequency of up to 8·6%.
