“…For example, colorectal adenomas and inflammatory bowel disease are conditions with a strong genetic component and have more or less proven associations with colorectal cancer (CRC) risk [34][35][36][37]. First-degree relatives of colorectal adenoma cases are at an increased risk of adenoma and CRC (relative risk, RR = 2.27 and 1.56, respectively [38]) and patients with ulcerative colitis (UC) have a CRC risk that is nearly six times higher than that in the general population [39]. Interestingly, recent GWA studies have identified common risk factors for CRC, colorectal polyps and UC.…”
