If a woman is diagnosed with endometrial polyps, then the condition is benign. If there are symptoms such as irregular vaginal bleeding, increased menstrual flow, or prolonged menstruation, endometrial polyps should be considered. It is advised to undergo diagnostic curettage or hysteroscopic endometrial polyp electrosurgical resection, and the removed tissue should be sent for pathological examination. Whether it is benign or malignant is mainly determined by the pathological examination as the final diagnostic basis. If confirmed as endometrial polyps, then it is benign. If precancerous lesions are present or if it is confirmed as malignant tumor, the case will be described in detail.
