Cervical conization effectively reduces the risk of cancer developing or spreading but it causes an increased risk of premature birth in future pregnancies.[2][3]
The chances of cancer recurrence and premature birth depends on the type of conization. Cold knife conization is associated with 7% chance of the cancer recurring and 16% chance of premature birth, laser conisation comes with 6% cancer recurrence and 13% premature birth, and loop excision comes with 10% recurrence and 11% premature birth.[2][3]
