Whether colorectal polyps are precursors of cancer (precancerous lesions) is mainly judged by the type of polyps, simple hyperplastic polyps and inflammatory polyps do not belong to precancerous lesions; adenomatous polyps belong to precancerous lesions. 1. Simple hyperplastic polyps and inflammatory polyps are epithelial cell hyperplasia caused by chronic inflammation stimulation and accompanied by certain inflammatory cells, the corresponding condition is not precancerous, and will not have much problem, usually surgical excision can be cured. 2. Adenomatous polyp itself belongs to pre-cancerous lesions, which may become cancerous if it is not controlled in time. After the discovery of the lesion, radical resection is needed through surgery, and radiotherapy should be actively carried out if there is cancerous lesion. If polyps are found in the large intestine, some of them need to be taken through colonoscopy to do pathology, and after determining the condition, the next step of treatment should be carried out.
