Conization in Turkey: what it is and how it works
Conization (also called cone biopsy or cervical conisation) removes a cone-shaped piece of tissue from the cervix, the neck of the womb. The piece includes the surface where abnormal cells grow and a short length of the canal above it. It does two things at once: it treats pre-cancerous change (cervical intraepithelial neoplasia, CIN) by taking it out, and it sends the removed tissue to a pathologist, who checks whether the change is more serious than the earlier biopsy suggested and whether the edges are clear. The operation is short and, in most cases, done as a day procedure.
This guide explains how conization is carried out, which technique is used when, what the evidence says, what it costs in Turkey compared with the UK, US and Germany, how recovery goes and what it means for pregnancy. It does not replace advice from your own gynaecologist. For the wider range of women's health care see our overview of gynaecology treatments in Turkey.
Why would you need a conization?
Most women reach conization through a screening pathway: an abnormal smear or a positive high-risk HPV test, then a colposcopy in which the cervix is examined under magnification and biopsies are taken. Conization is usually advised when biopsies show high-grade change (CIN 2 or CIN 3), when the colposcopy could not see the whole area, when the smear and biopsy results do not match, when glandular cell abnormality is suspected, or when an early cancer needs to be excluded or treated. Low-grade changes often settle by themselves and are normally watched, not cut. Guidance from bodies such as the NHS cervical screening programme and ASCCP in the US is clear that treatment should follow a confirmed result, not a single smear alone.
Which technique is used: LEEP, cold knife, laser or needle?
There are four ways to take the cone. LEEP (loop electrosurgical excision procedure, also called LLETZ) uses a thin wire loop with electric current and is the most common. A cold knife cone uses a scalpel and gives an undamaged specimen, so it is often chosen when glandular disease or early cancer is suspected and a deeper cone is needed. Laser cone uses a focused beam and is less widely available. A needle excision (NETZ) uses a straight needle electrode for a narrow cone. Your surgeon chooses based on the size and depth of the area, the cell type and whether you may become pregnant. The techniques compared in more detail are below; our page on LEEP covers the loop method.
| Technique | Best suited to | Typical limits |
|---|---|---|
| LEEP (loop) | Most CIN 2 and CIN 3 lesions on the cervix surface | Heat can affect the edges of the sample; deep canal disease is harder to reach |
| Cold knife cone | Glandular disease, suspected early cancer, deep lesions | Usually general anaesthesia; more bleeding; a longer day stay |
| Laser cone | Precisely shaped removal, selected cases | Needs specific equipment; less widely available |
Does conization work, and what does the evidence say?
Excision treatment is the standard of care for high-grade cervical change. Studies show that most women are cleared of CIN 2 and CIN 3 after one procedure, and that treatment greatly reduces the chance that change progresses to cervical cancer. A small share of women have abnormal cells at the edge of the cone or later recurrence, which is why follow-up testing matters: the NHS advises a test of cure with HPV testing, usually six months after treatment, and further annual checks if the result is not clear. Evidence is stronger for LEEP and cold knife than for laser, and the choice between them makes less difference to clearance than the quality of the surgeon and the pathology. HPV vaccination does not replace treatment but lowers the chance of new changes.
Conization cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for the procedure including pathology of the specimen, not hospital quotes.
| Country | Approximate cost range |
|---|---|
| Turkey | €600 – €2,500 |
| United Kingdom (private) | €1,500 – €4,500 |
| United States | €3,000 – €9,000 |
| Germany | €1,200 – €4,000 |
What changes the price: the technique (a cold knife cone in an operating theatre costs more than an office LEEP), the type of anaesthesia, whether a day stay is needed, the pathology report and whether a colposcopy or HPV test is part of the package. Ask whether the histology report is included and whether the price covers a follow-up visit.
Who is a good candidate for conization, and who is not?
You are a candidate if a recent biopsy or colposcopy shows high-grade change or a glandular abnormality, and if the doctor believes the whole area can be removed. Conization is not suitable during pregnancy except in rare cases, and it is delayed when there is an untreated cervical or vaginal infection. If the abnormality is large, extends far into the canal or has features of invasive cancer, a more extensive operation may be needed, such as a hysterectomy (see hysterectomy) or a trachelectomy to preserve fertility; this is decided by a gynaecological oncologist. Women who want children should tell the surgeon, because the depth of the cone can be kept as small as safely possible.
What happens during conization, step by step?
Before the procedure you are asked about your cycle, medicines and pregnancy possibility, and a colposcopy may be repeated on the day. For a LEEP, local anaesthetic is injected into the cervix; you may feel pressure or a brief cramp. The surgeon applies a dilute iodine or vinegar solution to show the abnormal area, removes the cone with the loop, seals the surface with a heated ball or cautery to stop bleeding and places the tissue in fixative for the laboratory. A LEEP takes about 10 to 20 minutes. A cold knife or laser cone is done under general or spinal anaesthesia, takes about 20 to 40 minutes, and the surface may be closed with stitches or a haemostatic paste. Most women go home the same day.
Recovery after conization: what to expect week by week
Expect period-like cramps for a day or two and a brownish, watery or blood-stained discharge for two to four weeks as the surface heals, with a small chance of heavier bleeding when the scab separates around days seven to ten. Most women return to desk work within one to three days. For about four weeks it is usual to avoid tampons, sexual intercourse, swimming and strenuous exercise, according to NHS advice, to lower the risk of infection and bleeding. Use pads and simple painkillers; call the team for heavy bleeding, fever or foul-smelling discharge. The first period afterwards may be heavier or late. Your next check, with an HPV or smear test, is normally about six months later.
Conization and pregnancy: what does it change?
Many women conceive and carry normally after conization. Research, summarised by the Royal College of Obstetricians and Gynaecologists and others, shows that excision slightly raises the chance of preterm birth and late miscarriage, and the risk increases with the depth of tissue removed and with repeated procedures. This is why surgeons try to remove only what is needed, particularly in younger women. Fertility itself is rarely affected, though scarring can narrow the cervical canal or reduce mucus. If you are pregnant after conization, tell your midwife; some units monitor cervical length. Women who are planning a pregnancy should discuss timing and follow-up before treatment.
Risks and complications of conization
Common effects are discharge, spotting and cramps. Less common problems are bleeding that needs treatment (around the first two weeks), infection, narrowing of the cervical canal (stenosis), pain with periods and, later, cervical weakness in pregnancy. Rare complications include damage to the bladder or bowel and anaesthetic problems. The risk of bleeding and stenosis is higher with a deeper or knife cone. The NHS, the ASCCP and the RCOG describe these risks and advise follow-up screening. Ask the team how they handle heavy bleeding after you have left the hospital and whether you will be near a clinic during the first ten days.
How to choose a team in Turkey, and what to ask
Check that the doctor is an obstetrician-gynaecologist experienced in colposcopy, that the clinic has a pathology laboratory with a written report, and that you receive your biopsy results, a clear plan and a price before you travel. Red flags include advising a cone without any biopsy, no histology of the removed tissue, and no plan for follow-up. If a fibroid or other uterine finding is raised at the visit, ask whether it needs separate treatment such as a hysteroscopic myomectomy.

Frequently asked questions
Conization, or cone biopsy, removes a cone-shaped piece of the cervix. It treats pre-cancerous cell change and gives the pathologist tissue to check whether the change is more serious than first thought.
It is the standard treatment for high-grade cervical change, and most women are cleared after one procedure. A small share have abnormal cells at the edge or later recurrence, so follow-up HPV or smear tests are advised.
Approximate ranges are €600 to €2,500 in Turkey, against about €1,500 to €4,500 privately in the UK. The price depends on the technique, the anaesthesia and whether the histology report is included.
Local anaesthetic is used for a LEEP, and most women feel pressure or a brief cramp. A cold knife or laser cone is done under general or spinal anaesthesia. Period-like cramps for a day or two are common afterwards.
Most women return to desk work in one to three days. Discharge lasts two to four weeks, and tampons, sex and swimming are usually avoided for about four weeks.
Yes, most women conceive and carry normally. Excision slightly raises the risk of preterm birth, more so with deeper or repeated cones, so tell your midwife about the procedure.
LEEP uses an electrified wire loop and is the most common. A cold knife cone uses a scalpel, usually under general anaesthesia, and suits deeper lesions or glandular disease.
Common effects are discharge and cramps. Bleeding, infection, narrowing of the cervical canal and, later, preterm birth in pregnancy are less common. Rare complications involve nearby organs.
The pathology report usually takes about one to two weeks. It shows whether the abnormal cells were fully removed and whether anything more serious was found.
A LEEP usually needs two to four days for the procedure and a check. A cold knife cone may need three to five days, and it is wise to stay near the clinic for the first days of healing.
