A colonoscopy is a procedure undertaken by a physician to visualize the interior of the colon and rectum. This examination is performed using a long, flexible tube with a camera attached, which is inserted into the anus and advanced through the large intestine. The physician performing this procedure can identify abnormalities such as polyps, tumors, inflammation, or bleeding.
The value of this medical investigation lies in its ability to detect precancerous growths, allowing for their removal before they become malignant. It also enables the diagnosis of various gastrointestinal conditions, including inflammatory bowel disease and diverticulitis. Regular screenings are recommended for individuals over a certain age, as well as those with a family history of colorectal cancer or specific bowel-related symptoms. Early detection significantly improves treatment outcomes and reduces the risk of advanced disease.
