Cervical cancer is the fourth leading cause of cancer death in women worldwide, and cervical intraepithelial neoplasia (CIN) can progress to cervical cancer. Therefore, timely treatment of CIN is critical in preventing the occurrence of cervical cancer. With the implementation and promotion of the World Health Organization's 2030 Global Strategy for the Elimination of Cervical Cancer, an increasing number of women are detecting and treating CIN at an earlier stage. Common treatment methods include ablation treatment and excision treatment, but for women who are planning to have children, the risk of cervical insufficiency and pregnancy complications is greatly increased after excisional treatment, so ablation treatment seems to be a better choice.
