Cervical conization is mainly indicated for patients with high degree of cervical squamous intraepithelial lesions, and the residual cervical stump after cervical conization is likely to develop cervical lesions again, which is also called recurrence. After conization, regular annual cervical cancer screening, including cervical liquid-based cytology and cervical HPV testing, is still required. The remaining cervical tissue may still have cervical lesions again and may still be repeatedly infected with HPV, leading to cervical lesions, and even in patients who have had a hysterectomy or a total hysterectomy without a cervix, the residual stumps may also cause lesions. In the future, regular annual cervical cancer screening, if suspicious cells are found in cytological examination and HPV test is found positive for high-risk types, biopsy is still needed to clarify whether there are cervical lesions and whether they are recurrent.
