Colorectal cancer, the second-most deadly cancer globally, credited with over 1.7% of all deaths, is tackled predominantly with colonoscopies in the US. Recent randomized controlled trials have proved ambiguous, querying the cost-effectiveness and efficiency of the invasive procedure. This procedure operates on the adenoma-carcinoma hypothesis, removing polyps formed by mutant cells that could develop into cancer. Alternative screening procedures include the occult blood test and sigmoidoscopy, both less invasive and cheaper.
