What is Adenoma Detection Rate?

An adenoma is a benign tumor or growth that is identified and can usually be removed during a colonoscopy. Most colon cancers develop from adenomatous polyps. If a benign adenoma is left to grow in the colon, it can become malignant over time. This is why screening and surveillance colonoscopies are so important for you to have done.

Adenoma detection rate (ADR) is the widely accepted national benchmark on quality for screening colonoscopy. A physician’s adenoma detection rate is the proportion of individuals undergoing a complete screening colonoscopy who have one or more adenomas, or polyps, detected.
