However, it may also be due to precancerous endometrial cancer, or endometrial cancer, endometrial polyps can cause vaginal bleeding. In this case, it is important to go to the hospital as soon as possible for an ultrasound examination, mainly to check whether the endometrium in the uterine cavity is thickened and whether there are polyps.
