If colonoscopy reveals polyps in the colon or rectum, not all polyps need to be removed, because some small polyps are too small to be cancerous, so they can be removed after they grow up, but if some polyps are found to be adenomatous polyps, it is recommended to remove them in time. polyp has a higher chance of malignant transformation. Small polyps do not need to be removed, such as inflammatory and hyperplastic polyps less than 0.5cm in diameter, which can be reviewed without treatment, such as single small polyps without a family history of colorectal cancer, which can be reviewed without changes in dynamic observation.
