Endometrial polyps are deformations that occur in the uterine cavity ( within the endometrium, the lining that covers the inside of the uterus ). They can be of different shape and size, and grow slowly, but sometimes they can get to fill the endometrial cavity. The endometrial polyp is painless and usually does not cause problems, appearing, especially in women past menopause. Signs of suspicion are: vaginal bleeding during or after menopause, excessive menstrual bleeding, heavy menstrual periods or longer than usual, cramping during or between periods, etc. Treatment or surgery for endometrial polyps usually requires its extirpation. The operation of endometrial polyp is done by hysteroscopy.
