What is endoscopic cancer screening and surveillance?
- Endoscopic screening for premalignant or malignant conditions is the one-time application of a test to search for lesions in asymptomatic persons in the hope that an early diagnosis will have an effect on disease outcomes.
- Endoscopic surveillance is testing patients with known premalignant or malignant conditions repeatedly over time to search for additional lesions in patients at increased risk.
