A colonoscopy is an examination of the large intestine (colon) and rectum using a flexible camera called a colonoscope. It is commonly used to investigate gastrointestinal symptoms, screen for colorectal cancer, and identify and remove certain types of polyps.
Many colorectal cancers develop from precancerous polyps over time. During a colonoscopy, polyps that are appropriate for removal can often be removed during the same procedure, which may reduce the risk of developing colorectal cancer.
The procedure is performed using high-definition video equipment. Sedation options are discussed with each patient, and the most appropriate approach is determined based on the individual’s medical history and the procedure being performed.
Regular colorectal cancer screening may help detect cancer at an earlier stage, when treatment is often more effective, and may help identify precancerous polyps before they become cancerous. Screening recommendations depend on factors such as age, family history, personal medical history, and individual risk factors.
A physician consultation is required to determine whether colonoscopy is appropriate for your specific situation.
