A client suspected of having colorectal cancer requires which diagnostic study to confirm the diagnosis?

The answer is Colonoscopy. The Colonoscopy is a wide-ranging analysis of the large intestine. A flexible lighted tube fitted with a tiny camera is placed in over the anus. The inside of the rectum and colon can be observed for polyps, cancer or Chron’s disease. The tissue and polyps can be detached throughout the process.
