Cervical Conization (Cone Biopsy and LEEP)

Conization removes a cone-shaped piece of the cervix that contains the transformation zone, the area where abnormal cells develop. It both treats high-grade precancerous change (CIN 2, CIN 3 or adenocarcinoma in situ) and provides a full specimen for the pathologist.

In most women it removes the abnormal tissue completely and prevents progression to cancer. It does not clear the HPV virus itself, so follow-up testing is essential, and removing deeper cones slightly raises the chance of preterm birth in later pregnancies.

What Cervical Conization (Cone Biopsy and LEEP) involves

With you positioned as for a smear, a speculum is placed and the cervix is painted with acetic acid and iodine under colposcopy to outline the abnormal area. Local anaesthetic with adrenaline is injected into the cervix. In a loop excision (LEEP or LLETZ) a thin electrified wire loop sweeps through the tissue in a few seconds, removing a disc 7 to 15 mm deep depending on how far the transformation zone extends into the canal. In a cold knife cone the surgeon cuts a deeper, precisely shaped cone with a scalpel under general anaesthesia. The raw base is sealed with ball diathermy or paste, the specimen is marked for orientation, and a sampling of the canal above may be taken.

Who is a good candidate for Cervical Conization (Cone Biopsy and LEEP)?

Recommended after colposcopy and a small biopsy have confirmed, or strongly suggest, high-grade change.

• Biopsy-proven CIN 2 or CIN 3
• Adenocarcinoma in situ, where a deeper, intact specimen is preferred
• A high-grade smear with an abnormal area extending out of view into the canal
• Persistent discrepancy between smear, colposcopy and biopsy findings
• Suspected very early (microinvasive) cancer, for diagnosis and sometimes definitive treatment

It is usually not the right choice if:

• Low-grade change (CIN 1), which usually clears by itself and is monitored
• Pregnancy, unless invasive cancer is suspected
• CIN 2 in young women who wish to have children, where observation is often reasonable
• Active cervical or pelvic infection until treated
• Obvious invasive cancer, which needs staging and different treatment

Technique options

• LEEP or LLETZ: Loop excision under local anaesthesia; the standard for most squamous precancer.
• Cold knife conization: Clean margins without heat damage; favoured for glandular lesions and suspected microinvasion.
• Laser conization: Precise with little bleeding; needs specific equipment and takes longer.
• Top-hat excision: A second, smaller loop pass higher in the canal when disease extends upward.
• Hysterectomy: Considered for adenocarcinoma in situ once childbearing is complete, not for ordinary CIN.

What happens during your treatment

A loop excision takes 10 to 20 minutes in an outpatient room; you feel a cramp with the injection and sometimes a racing heart from the adrenaline for a minute. A cold knife cone takes 20 to 40 minutes under general or spinal anaesthesia as a day case.

Preparing for your trip

Plan for 4 to 7 days in Istanbul. Your surgeon reviews photographs and your medical history before you book, and you meet in person the day before surgery for examination, marking and consent with a professional interpreter.

• Stop smoking and nicotine at least four weeks before and after surgery; it is the single biggest avoidable cause of wound problems
• Tell the team about every medicine and supplement you take; blood thinners, some herbal products and hormone treatment may need to be paused on your doctor's advice
• Arrange for someone to travel with you or to be reachable, and keep the first days at home free of work and lifting
• Book a changeable return flight; your surgeon confirms when you are fit to fly

Recovery and results

Expect period-like cramps for a day or two and a watery, brown or blood-stained discharge for 2 to 4 weeks. Avoid tampons, intercourse, swimming and baths for 4 weeks so the cervix can heal. Heavier bleeding sometimes occurs around day 7 to 14 when the scab separates. Most women return to work the next day after LEEP. A test of cure with HPV testing and cytology is done at about 6 months.

• Back to everyday activity: 1 to 2 days; restrictions for 4 weeks
• When results show: Pathology result in 5 to 10 days
• How long they last: Cure in about 90 percent; HPV follow-up needed

Safety, risks and revision policy

It is a minor procedure with a low complication rate; the pregnancy issue deserves a frank discussion if you plan children.

• Bleeding during or 1 to 2 weeks after the procedure, occasionally needing packing or a stitch
• Infection with offensive discharge and pain
• Narrowing of the cervical canal (stenosis), causing painful periods or difficult future smears
• A modestly increased risk of preterm birth or late miscarriage, related to the depth removed
• Incomplete excision with positive margins, needing closer follow-up or repeat treatment
• Recurrence of abnormal cells in about 5 to 10 percent

Cost of Cervical Conization (Cone Biopsy and LEEP) in Türkiye

Clinic-Y does not publish a single price for Cervical Conization (Cone Biopsy and LEEP), because the honest figure depends on your case. What moves it:

• Loop excision under local versus cold knife cone under anaesthesia
• Colposcopy and pathology fees
• Whether HPV typing and endocervical sampling are included
• Day-case theatre and anaesthetist charges for knife or laser cones
