Cervical erosion degree III is the most powerful. In degree III cervical erosion, the area of cervical erosion is more than 2/3 of the total area of the cervix. Cervical cervical erosion of degree III is mainly due to the outward migration of the cervical columnar epithelium caused by the strong secretion of estrogen in the body, resulting in red granular changes in the cervix, which can easily induce the occurrence of cervical cancer if combined with hpv infection. Cervical erosion of degree III is often combined with different degrees of cervicitis, and repeated stimulation of inflammation without timely treatment may lead to painful intercourse and bleeding during intercourse, and in serious cases, may induce cervical cancer. It is recommended to use physical therapy such as laser and freezing to avoid cancerous changes. It is advisable to reduce the number of sexual intercourse and to do a good job of cleaning the vulva for observation purposes, and to go to the hospital regularly for recurrence in order to observe whether the cervical erosion is expanding and whether there is abnormal hyperplasia.
