Glandular squamous does not necessarily develop into cancer. Glandular squamous itself is not a precancerous lesion, it is just a manifestation of chronic cervicitis. The appearance of this glandular squamous manifestation should be reviewed regularly. It is the most common local feature of the inflammatory process of cervical erosion, with red lesions on the surface of the cervix, suggesting that the squamous epithelium is shed and replaced by columnar epithelium. Squamous epithelial metaplasia is a change in the healing process of celiac disease and has no tendency to form cancer, is not a precancerous lesion and is not the same as the concept of atypical hyperplasia.
