Patient's question:
NoDoctor's answer:
Hello, cervical erosion is caused by chronic cervical inflammation, where the deep tissue of the cervix is difficult to eliminate due to inflammation. The squamous epithelium on the surface of the cervix falls off due to nutritional disorders. The denuded area is gradually covered by columnar epithelium that proliferates from the cervical canal. Since the columnar epithelium is very thin, it allows the underlying blood vessels and red stroma to be visible, making the erosion surface appear red and clearly demarcated from the surrounding normal squamous epithelium.
