Transitional lesions

The most common site of cervical lesions is the transitional zone between the original squamous epithelium-columnar epithelium junction and the existing squamous epithelium-columnar epithelium junction. Because the surface of the cervix is ​​covered with stratified squamous epithelium, the defense ability is better, while the inner layer of the cervical canal is covered by a single layer of columnar epithelium. When the cervical epithelial metaplasia is active, some foreign pathogens are stimulated, or the transition zone changes repeatedly. Active immature cells or proliferating squamous epithelium in the transition zone can develop towards cervical lesions. Therefore, the cervical canal is the source of cervical lesions, and cervical canal medication is the key to completely cure cervical erosion.
