Cervical transformation zone three must be lesions?

Cervical transformation zone type III is not necessarily a lesion.

Cervical transformation zone type III is a descriptive term for colposcopy. It refers to the complete disappearance of the squamous column junction of the cervix. Generally, it is related to physiological factors. For example, women in menopause due to low estrogen levels can lead to the retraction of the squamous column junction into the cervical canal, so it cannot be seen during colposcopy. However, trauma, severe infection, precancerous lesions and other factors can also lead to the withdrawal of the squamous column junction into the cervical orifice.

Therefore, when patients with cervical transformation zone type III appear, pathological biopsy should be performed to confirm the diagnosis.
