Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine). [5] Signs and symptoms may include blood in the stool , a change in bowel movements , weight loss, abdominal pain and fatigue. [ 9 ]
Serrated polyposis syndrome often does not cause symptoms. The risk of colon cancer is between 25 and 40%. [8] Sessile serrated polyps, as seen during endoscopy or colonoscopy, are flat (rather than raised) and are easily overlooked. Serrated lesions range in size from small (<5 mm) to large, and often have a "mucous cap" overlying the polyp.
A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
A new study shows that stress can affect colorectal cancer progression by altering gut balance. It comes in the wake of research highlighting the importance of sleep to gut health and tumor ...
Several SSLs confer a higher risk of subsequently finding colorectal cancer and warrant more frequent surveillance. The surveillance guidelines are the same as for other colonic adenomas . The surveillance interval is dependent on (1) the number of adenomas, (2) the size of the adenomas, and (3) the presence of high-grade microscopic features.
As such, regular colorectal examinations or fecal occult blood testing are necessary for catching the disease in its early stages. However, there are some signs that can indicate colon cancer; they include abrupt changes in bowel habits, bleeding from the rectum, black stools, frequent constipation, and mucus in the stools.
The sigmoid colon is completely surrounded by peritoneum (and thus is not retroperitoneal), which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.
Although colon cancer is usually not found in polyps smaller than 2.5 cm, all polyps found are removed since their removal reduces the likelihood of future colon cancer. When adenomatous polyps are removed, a repeat colonoscopy is usually performed three to five years later. [citation needed] Most colon polyps can be categorized as sporadic.
