Cervical conization refers to an excision of a cone-shaped portion of tissue from the mucous membrane of the cervix. Conization is used for diagnostic purposes as part of a biopsy and for therapeutic purposes to remove pre-cancerous cells ( cervical intraepithelial neoplasia) or early stage cervical cancer. ^[1]

Types include: ^{[2] [3]}

• Cold knife conization (CKC)
• Laser conization
• Loop electrical excision procedure (LEEP)

Side effects

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]}
