Colonoscopy Pros and Cons List
Colorectal cancer is believed to be the second principal source of cancer deaths in American. A colonoscopy is the most accurate test used to check colorectal cancer. Notably, carrying out a colonoscopy can help identify and eliminate polyps which are the pre-cancerous lesions. Basically, colonoscopy is a screening test offered for colorectal cancer and is usually conducted by a doctor through the insertion of a colonoscope which is a long thin and flexible tube, into the colon via the rectum.
Colonoscopy is commonly recommended since it helps visualize the large intestines and also helps the doctor see down and across and the whole length of the colon. Nevertheless, this procedure requires ample preparation and sedation and also carries high risks like bleeding and perforation. Before colonoscopy is carried out various procedures such as emptying the bowels are carried out. The bowel is mostly emptied to rid the colon of any stool, and to ensure that the doctor has a clear view.
Bowel preparation is usually done a few days before a colonoscopy is achieved by ensuring the patient does not take any solid food. A strong laxative or a bowel preparation solution is also given to the patient the night before the test is carried out. Following the preparation directions is very vital, since an improperly prepared colon may block the polyps or other abnormalities.
