Rectal polyps should be endoscopically examined to confirm whether they are benign or malignant. If they are benign, they should be endoscopically resected and examined in time, and there is no relationship in this case. If the polyp is malignant, it is rectal cancer. If the pathologic diagnosis is rectal cancer, the problem will be more serious, and if it is considered carcinoma in situ, it can be endoscopically resected. If it is in situ cancer, it can be removed endoscopically. If it is progressive rectal cancer, laparoscopic or open radical rectal cancer surgery should be considered, and after surgery, according to the final stage, it will be decided whether or not to continue radiotherapy or chemotherapy. Therefore, if rectal polyps are found during physical examination, they should be actively treated because benign rectal polyps have a certain probability of malignant transformation. Endoscopic rectal polyp removal surgery is just a very simple operation, which can solve the worry of preventing cancer, so it is more advocated.
