Cervical bleeding may be caused by cervical leukoplakia, cervical cancer, cervical erosion, cervical ectropion and cervical polyps. The symptoms are usually as follows: i. irregular uterine bleeding; ii. excessive menstruation; iii. frequent menstruation. Cervical erosion is due to the chronic inflammatory period of the cervix with more purulent discharge, impregnating the epithelium of the ectocervix, causing it to lose its vitality and form peeling and ulceration, i.e., it becomes a bright red area with fine particles with luster around the ectocervix as often seen in clinical practice. Ectocervix, the cervix is torn during childbirth, induction of labor, abortion, if not timely surgical repair, later scar tissue contracture, so that the cervical ectocervix, if combined with infection to form chronic cervicitis, leucorrhea is purulent, and contact congestion. Cervical polyp inflammation is a factor of polyp formation, polyps originating from the mucous membrane of the uterine tube are soft, bright red, brittle in texture, bleeding when lightly touching the polyps, which can be found during gynecological examination. Cervical leukoplakia is a white opaque patchy lesion appearing in the vaginal part of the uterine cervix, the cause of which is not particularly clear and may be related to endocrine disorders, chronic stimulation of cervical inflammation, and the influence of vaginal trichomonas. Contact bleeding may be one of the early symptoms of cervical cancer, often bleeding after sexual intercourse or during vaginal examination.
