Colonoscopy: An Important Preventive Examination for Your Colon Health
A colonoscopy is one of the most important preventive examinations for the early detection of colon diseases, especially colon cancer. It allows a precise evaluation of the intestinal lining and the detection of potential abnormalities, such as polyps, which could develop into cancer over time. Colonoscopy is generally recommended starting at age 45, or earlier for patients with a family history or other risk factors. Early removal of benign polyps (precursors) can prevent the development of colon cancer.
In my practice, I emphasize providing patients with ample time and information to prepare for the examination. A thorough bowel cleansing is crucial for an accurate examination, as only a clear view of the entire intestinal lining allows reliable detection of possible changes. The colonoscopy is performed under sedation, ensuring the procedure is painless and comfortable for patients.
