One of the most effective ways to detect and prevent colon cancer is through a colonoscopy. As with all medical procedures, some preparations are needed before a colonoscopy can be carried out, with the main one being cleaning and emptying the colon.
A colonoscopy is a screening test to check for abnormalities in the colon and rectum. The procedure uses a long, flexible tube equipped with a light and camera—called a colonoscope—to see the colon and rectum from outside the body.
The colonoscopy procedure is the most accurate test to screen colon and rectum cancer. It is a tool that saves lives as it can detect pre-cancerous growths to be removed, before they potentially turn cancerous. Other reasons why it’s done include:
Your doctor may advise you to:
If you are taking any medications or supplements, make sure to inform your doctor as they may affect your colonoscopy procedure.
Before the colonoscopy procedure begins, you will be sedated to make you feel more comfortable. While laying on your side, the doctor will insert the colonoscope through the anus and all the way through the colon to examine the entire tract. Any abnormality, including bleeding or abnormal growths, will be examined. The doctor may remove samples of abnormal tissue or polyp during the procedure for biopsy.
After the colonoscopy, you will be taken to the recovery room. You may feel bloated, or you will pass gas a few hours following the procedure. Though highly unlikely for complications to occur in experienced hands, do remember to call your doctor if you notice excessive bleeding or persistent abdominal pain.
