Colonoscopy is a diagnostic procedure that is performed to examine the entire colon and rectum under direct visualization. By inserting a thin, flexible tube with a small light and camera at the end through the anus and rectum until it reaches the beginning of the colon, we will be able to detect any abnormal growths that may be present in the large intestines.
During this examination, any polyp that is found will be removed to prevent colorectal cancer from potentially developing and a biopsy of the tissues can be carried out for further testing.
This is why colonoscopies are known to be highly effective and recommended for diagnosing colorectal cancer at an early stage, which leads to a better outcome for patients.
As colonoscopy is usually done under sedation, it is painless with only minor discomfort such as bloating after the procedure.
