Benign tumors do not invade nearby tissues or spread to other parts of the body like malignant cancer cells. Whether or not treatment for a benign tumor is necessary will depend on the nature and location of the tumor.

Artificial intelligence (AI), especially deep learning models, is a promising innovation in colonoscopy. Recent studies have shown that AI is not only accurate in detecting colorectal polyps but can also reduce the miss rate. However, the application of AI in real-time detection has been hindered by the heterogeneity of AI models and study designs as well as the lack of long-term results.
