A 2010 British study [3] showed sigmoidoscopy reduced "overall colorectal cancer incidence and mortality by 31 percent", and "incidence of cancer in just the lower part of the colon (or distal colon) was reduced by approximately 50 percent for those who underwent screening compared with those in the control group."
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases.

Ultrasound is the imaging modality of choice for diagnosis and exclusion of intussusception, due to its high accuracy and lack of radiation. The appearance of target sign (also called "doughnut sign" on a sonograph, usually around 3 cm in diameter, confirms the diagnosis.
The colon cut-off sign is a radiographic finding seen on abdominal radiographs and computed tomography scans. It is characterized by a marked dilatation of the transverse colon, with an abrupt transition to collapsed distal colon, particularly the splenic flexure. [1] This sign is indicative of underlying pathology, most commonly acute ...
Breast cancer, prostate cancer, and colorectal cancer are examples of cancer types that are prone to overdiagnosis. [10] The consequences of overdiagnosis and overtreatment resulting from cancer screening can lead to a decline in quality of life, due to the adverse effects of unnecessary medication and hospitalization.

A human colon is considered abnormally enlarged if it has a diameter greater than 12 cm [3] in the cecum (it is usually less than 9 cm [4]), greater than 6.5 cm [3] in the rectosigmoid region and greater than 8 cm [3] for the ascending colon. The transverse colon is usually less than 6 cm in diameter. [4] A megacolon can be either acute or ...
The M2-PK Test is a non-invasive screening method for the early detection of colorectal cancers and polyps which are known to be the precursors of colorectal cancer. The M2-PK Test which is used for stool analysis is available either as fully quantitative ELISA Test or as a rapid test that can be performed by any general practitioner without the need of a laboratory or any additional equipment.
Chilaiditi syndrome is a rare condition when pain occurs due to transposition of a loop of large intestine (usually transverse colon) in between the diaphragm and the liver, visible on plain abdominal X-ray or chest X-ray. [1] Normally this causes no symptoms, and this is called Chilaiditi's sign. The sign can be permanently present, or ...
