Endometrial polyps are not usually cancerous within 5 years. Most endometrial polyps are clinically benign and the chance of cancer is relatively low. Endometrial polyp is a kind of lesion formed due to the abnormal proliferation of the endometrium, which can be single, that is, one polyp, or multiple endometrial polyps. The common clinical manifestations of endometrial polyps are increased menstruation, trailing menstruation or irregular vaginal bleeding. Some people have no obvious symptoms and may be found during a physical examination. Endometrial polyps are treated by scraping the uterus, or by more advanced hysteroscopic means, in which the endometrial polyps are scraped off and sent for pathologic examination. For patients with endometrial polyps, it is recommended to go to the hospital in time, according to the size of the endometrial polyp, the patient’s physical condition and other active treatment, to reduce the chance of cancer.
