LEEP and Conization: Diagnosis, Treatment and Follow-Up of Cervical Cell Changes
The cervix is the lower part of the uterus that opens into the vagina. Cellular changes may develop in this area, most commonly in association with human papillomavirus, or HPV. Some of these changes may resolve on their own, while others may progress over time into precancerous lesions. LEEP and conization are important procedures used to remove abnormal or precancerous tissue from the cervix.
Does an abnormal Pap smear always mean cancer?
No. An abnormal Pap smear or a positive HPV test does not usually mean cancer. These results indicate that there may be changes in the cervical cells and that further evaluation may be needed. The goal is to detect and treat risky cell changes before cervical cancer develops.
What is LEEP?
LEEP stands for “Loop Electrosurgical Excision Procedure.” It is a procedure in which a thin wire loop carrying an electrical current is used to remove abnormal tissue from the cervix. The removed tissue is then sent for pathological examination.
LEEP may be recommended when:
Colposcopy and biopsy show high-grade cervical cell changes such as CIN 2 or CIN 3
Pap smear, HPV testing and biopsy results suggest a risk that requires treatment
The abnormal area needs to be both removed and examined under the microscope
A diagnostic and therapeutic excisional procedure is appropriate
LEEP is often performed as an outpatient procedure and may be done under local anesthesia. In suitable patients, it can serve both diagnostic and therapeutic purposes.
What is conization?
Conization, also called cone biopsy, is the removal of a cone-shaped piece of tissue from the cervix. The specimen may include both the surface of the cervix and tissue extending into the cervical canal. This allows a deeper and wider pathological assessment.
Conization may be preferred when:
The entire lesion cannot be seen during colposcopy
The abnormal cells are suspected to extend into the cervical canal
Pap smear, HPV, colposcopy and biopsy results are inconsistent
Glandular cell abnormality or adenocarcinoma in situ is suspected
Microinvasive cancer needs to be excluded or evaluated
Previous treatment results or surgical margins require further clarification
Conization can be performed with a cold knife, laser or, in selected cases, using a LEEP technique. In everyday clinical language, the term “conization” often refers to cold knife conization.
What is the difference between LEEP and conization?
LEEP and conization are similar in that both remove cervical tissue and provide a specimen for pathological examination. Both may be diagnostic and therapeutic. However, there are important differences.
LEEP is generally used to remove more superficial or limited areas of abnormal tissue. It is commonly performed in an outpatient setting, often under local anesthesia. The procedure is relatively short and recovery is usually straightforward.
Conization is usually preferred when a larger or deeper specimen is needed. It may be more appropriate when the lesion extends into the cervical canal, when colposcopy is inadequate, or when there is a stronger need to evaluate for possible early invasive disease. In cold knife conization, the tissue margins may be less affected by heat, which can be helpful for pathological margin assessment in selected cases.
In short: LEEP is an effective and practical treatment option for many high-grade cervical cell changes. Conization is often chosen when a deeper, wider or more diagnostically precise excision is needed.
Do cervical precancerous changes cause symptoms?
Precancerous cervical cell changes usually do not cause symptoms. This is why regular Pap smear and HPV screening are so important. Many patients are evaluated after an abnormal screening result despite having no complaints.
In some cervical conditions, the following symptoms may occur:
Bleeding after sexual intercourse
Bleeding or spotting between periods
Bleeding after menopause
Unusual or foul-smelling vaginal discharge
Pelvic pain
These symptoms do not necessarily mean cancer. They may be related to infection, polyps, hormonal causes or other gynecological conditions. However, persistent or unexplained bleeding should be evaluated by a gynecologist.
How is the diagnosis made?
Diagnosis usually involves several steps.
The first step is a Pap smear and/or HPV test. A Pap smear evaluates cervical cells under the microscope. An HPV test checks for high-risk HPV types associated with cervical cancer.
If abnormal results are found, colposcopy may be recommended. Colposcopy is a detailed examination of the cervix using a special magnifying instrument. Biopsies can be taken from suspicious areas. In some cases, sampling from the cervical canal may also be needed.
LEEP or conization may be used in selected patients to confirm the diagnosis and provide treatment at the same time. The pathological examination of the removed tissue helps determine the grade and extent of the lesion and whether there is any suspicion of cancer.
How is treatment chosen?
Treatment is not based on a single test alone. The patient’s age, pregnancy plans, Pap smear result, HPV type, colposcopy findings, biopsy result, location of the lesion and previous screening history are evaluated together.
Low-grade changes do not always require immediate treatment. In some patients, follow-up may be enough, especially because mild changes can regress over time, particularly in younger patients.
High-grade changes may require excisional treatment such as LEEP or conization. The goal is to remove the precancerous tissue and allow detailed pathological examination.
What is normal after the procedure?
After LEEP or conization, mild pelvic discomfort, menstrual-like cramps, spotting, brown or dark discharge, or watery discharge may occur for several days to a few weeks. These findings are often part of the normal healing process.
Patients may be advised to avoid sexual intercourse, tampon use, vaginal douching, swimming and heavy exercise for a certain period. This period is often a few weeks but may vary depending on the type of procedure and the individual patient.
When should a doctor be contacted?
Medical advice should be sought promptly if any of the following occur after the procedure:
Heavy bleeding
Foul-smelling discharge
Fever
Severe pelvic or abdominal pain
Pain that does not improve with medication
Dizziness, fainting or feeling generally unwell
These symptoms may require evaluation for infection, bleeding or another complication.
Why is follow-up so important?
Even after abnormal tissue has been removed by LEEP or conization, follow-up is still necessary. HPV infection may persist, and abnormal cell changes can recur over time. Therefore, regular follow-up with Pap smear, HPV testing or cotesting is important.
The follow-up schedule depends on the pathology result, whether the surgical margins are clear, the HPV result, the patient’s age and previous history. Long-term surveillance is especially important after treatment for high-grade lesions.
Why should pregnancy plans be discussed?
LEEP and conization remove tissue from the cervix. Most patients can still have healthy pregnancies in the future. However, deeper or repeated procedures may increase the risk of cervical insufficiency, preterm birth or cervical narrowing. For this reason, treatment decisions should be individualized in patients who are planning pregnancy.
Conclusion
LEEP and conization are valuable procedures for diagnosing and treating cervical cell changes before cervical cancer develops. LEEP is usually more practical and suitable for many limited high-grade lesions, while conization is preferred when a wider, deeper or more diagnostically precise specimen is needed. The best approach is determined by evaluating Pap smear, HPV testing, colposcopy, biopsy results and the patient’s individual risk factors together.
Regular screening, accurate diagnosis, appropriate treatment and consistent follow-up are among the most effective ways to prevent cervical cancer.
