Most endometrial polyps are benign lesions, with a 0%-12.9% chance of malignancy, which increases with age. The chance of endometrial polyps becoming cancerous can reach 32% in women >65 years of age, endometrial cancers are more common in women 45-55 years of age, and plasmacytoid cancers are most common in women >65 years of age. When abnormal bleeding is present, it is important to perform ultrasound early, including removal of endometrial polyps, to avoid the development of more and more polyps, which can cause abnormal bleeding over time. With the passage of time, there is a chance that they may develop into cancer, so it is important to do early detection and early treatment.
