The vulnerable site of cervical lesions is the migratory zone between the squamous epithelium-columnar epithelium junction. The repeated changes in the migratory zone lead to a weakened immune system recognition response in the cervical transformation zone, which becomes a weak link and vulnerable to foreign pathogens and viruses. Therefore, the cervical os and the migratory zone are the source of cervical lesions and are the key sites for curing cervical lesions. What is the diagnosis of migratory lesions in general? Simple ectopic cervical columnar epithelium is a physiological phenomenon, and the degree of ectopic is not directly related to cervical cancer, nor does it need to be treated. Nowadays, there is a phenomenon of over-treatment of the so-called “cervical erosion”, which is not only misleading but also related to the lack of medical knowledge of women.

If you suspect that your cervix has problems, you can go to the hospital for relevant examinations.
