Endometrial polyps are caused by excessive growth of the endometrial lining, and can be single or multiple, with diameters ranging from a few millimeters to several centimeters. They can be pedunculated or sessile. Endometrial polyps smaller than one centimeter in diameter, if asymptomatic, have a natural resolution rate of about 27% within a year and a low rate of malignancy. If the polyp is large, greater than one centimeter, it requires hysteroscopic endometrial polypectomy or curettage. However, curettage has disadvantages, as it can easily miss polyps, and there is a high chance of recurrence after the surgery. Therefore, once an endometrial polyp larger than one centimeter is identified, it is advisable to promptly visit a hospital for examination and treatment. Postoperative treatment should be guided based on the pathological findings.
