It may be of different size and shape, and has a slow growth, but sometimes it can occupy the entire endometrial cavity. 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, cramps during or between periods, etc. Treatment or surgery for endometrial polyps usually require removal.
