Quick Answer: What is LEEP?
LEEP is a short procedure that removes abnormal surface tissue from the cervix with an electrically heated wire loop, both treating cervical dysplasia and sending tissue for laboratory testing. It usually takes place in a gynecologist's office or outpatient setting. The person stays awake with local anesthesia and may feel a brief pinch, pressure or warmth during removal.
What the research says
Excision is linked to a higher chance of preterm birth in later pregnancies, and the risk rises with the amount of tissue removed. A meta-analysis of 71 studies (65,082 treated and 6,292,563 untreated women) found preterm birth before 37 weeks in 10.7% vs 5.4% (relative risk 1.78, 95% CI 1.60–1.98). For large loop excision of the transformation zone, the relative risk was 1.56 (1.36–1.79), and it climbed with cone depth, reaching 4.91 (2.06–11.68) at 20 mm or deeper (Kyrgiou et al., BMJ, 2016; DOI). [2]
Most people are cleared by one excision, but a small share need more treatment. Across 97 studies and 44,446 women treated by excision, residual or recurrent CIN2+ occurred in 6.6% (95% CI 4.9–8.4), and the risk was higher when the edges of the removed tissue still contained abnormal cells (relative risk 4.8, 95% CI 3.2–7.2) (Arbyn et al., Lancet Oncology, 2017; DOI). [3]
A follow-up high-risk HPV test is a reliable guide to who needs further treatment. In 46 studies of 20,385 women, treatment failure occurred in 6.6%. High-risk HPV testing had a pooled sensitivity of 86.8% and specificity of 80.5%, and women with both negative margins and a negative HPV test had a failure risk of 0.3% (Bomans et al., Obstetrics & Gynecology, 2025; DOI). [4]
Key Takeaways
Feature | Details |
What it is | A procedure that uses an electrically heated wire loop to remove a thin layer of abnormal tissue from the surface of the cervix. [1] |
Why it is done | To treat and test abnormal cervical cells found on a Pap test or colposcopy; also used for some cervical polyps and genital warts. [1] |
Setting and anesthesia | Gynecologist’s office, hospital or outpatient setting; you stay awake with local anesthesia. [1] |
Duration | About 10 to 20 minutes. [1] |
Recovery | Cramps, discharge or spotting for one to three weeks; the cervix generally heals in four to six weeks. [1] |
Key limitation | LEEP removes abnormal cells but does not eliminate HPV; follow-up testing may be needed. [1] |
Main risks | Infection, bleeding and possible cervical weakening that may matter in a future pregnancy. [1] |
Why is LEEP performed?
LEEP may be recommended when a Pap test or colposcopy confirms abnormal cells on the cervix. It can remove a thin surface layer containing abnormal cells and provide tissue for testing. [1]
The procedure may also be used as a diagnostic and treatment tool for cervical polyps and genital warts. The exact recommendation depends on the findings, the person’s health history and the healthcare professional’s assessment. [1]
Cervical dysplasia is not the same as cancer
Cervical dysplasia means abnormal cells on the cervix. It is not cancer, but it can lead to cervical cancer over time without treatment. Removing and testing the tissue can help manage the abnormal cells and clarify what is present. [1]
What happens before LEEP?
Before the procedure, the healthcare professional checks for conditions that may affect timing or safety. Acute pelvic inflammatory disease and inflammation of the cervix, called cervicitis, are reasons not to have LEEP at that time. [1]
A pregnancy test may be needed. If someone is pregnant, the healthcare professional can recommend appropriate timing. LEEP is scheduled when the person is not on their period. [1]
Preparation checklist
Follow the treating team’s instructions because preparation differs between people. Instructions may include avoiding intercourse or vaginal creams for 24 hours, bringing a pad for discharge, discussing medicines that affect blood clotting, taking a pain reliever only if instructed and wearing loose-fitting clothing. [1]
Do not stop anticoagulants, aspirin or another prescribed medicine without direct instructions from the healthcare professional who manages it. Medication decisions should be individualized. [1]
Preparation topic | What it means |
Timing | The procedure is scheduled when you are not on your period; timing during pregnancy requires professional guidance. [1] |
Infection or inflammation | Acute pelvic inflammatory disease or cervicitis may mean LEEP should not occur until the issue is addressed. [1] |
Vaginal products | You may be asked to avoid intercourse and vaginal creams for 24 hours beforehand. [1] |
Discharge | Bring a pad to use after the procedure. [1] |
Medicines | Discuss anticoagulants, aspirin and other medicines that affect clotting. Follow the clinician’s instructions. [1] |
Comfort | A pain reliever may be recommended before the procedure; use only the medicine and timing advised by the healthcare professional. [1] |
Clothing | Loose-fitting clothing is easier to remove and replace with a gown. [1] |
Where does LEEP take place?
LEEP can occur in a gynecologist’s office, hospital or outpatient setting. The person usually goes home after the procedure once they feel ready. [1]
Ask whether you will need someone to accompany you, how long you should plan to be at the facility and what supplies to bring. The treating team’s instructions take priority over general information. [1]
What happens during a LEEP procedure?
LEEP begins much like a pelvic examination. You remain awake. You lie back with your feet in stirrups, and a grounding pad is placed on your thigh to protect you from the electrical current. A speculum gently widens the vagina so the cervix can be seen. [1]
A dilute acetic-acid or iodine solution may be placed on the cervix to make abnormal cells easier to see. A colposcope provides a magnified view and remains outside the body. [1]
Step 1: Numbing the cervix
Local anesthesia numbs the cervix. The injection can cause a brief sharp pinch followed by a quick burning sensation. A racing heartbeat or dizziness related to epinephrine may occur briefly. [1]
Tell the healthcare professional if you feel intense pain at any point. Local anesthesia is intended to make the procedure tolerable, but each person experiences sensations differently. [1]
Step 2: Removing the abnormal tissue
After the cervix is numb, the healthcare professional places an electrically heated wire loop across the cervix. The loop cuts away a thin layer of surface tissue. Sometimes a second loop is used to reach a little higher in the cervix. The tissue is sent for testing. [1]
You may notice warmth, pressure or a light vibration. Remaining still during tissue removal helps the healthcare professional work safely. [1]
Step 3: Helping control bleeding
A medicated iron paste may be applied to the treated area to stop and help prevent bleeding. [1]
How long does LEEP take?
The procedure takes about 10 to 20 minutes. You can usually leave when you feel ready, although some people rest at the office first while aftercare instructions are reviewed. [1]
Figure 2. The procedure includes visualization, local anesthesia, tissue removal with an electrified loop, laboratory testing and bleeding control.
Is LEEP painful?
Local anesthesia numbs the cervix, so many people feel little or no pain during tissue removal. The numbing injection may briefly sting or burn. Pressure or warmth may occur while the loop removes tissue. [1]
Pain tolerance varies. Let the healthcare professional know if you begin to feel intense pain during the procedure. [1]
What are the benefits and risks of LEEP?
LEEP is very safe, and complications are rare. It can be performed without general anesthesia. As with any surgery, infection and bleeding are possible. [1]
One pregnancy-related concern is that LEEP may weaken the cervix and contribute to preterm birth in a future pregnancy. Discuss pregnancy plans and concerns with the healthcare professional before the procedure. [1]
The benefits may outweigh the risks for people who need abnormal tissue removed and tested. LEEP is one of the most effective ways to remove precancerous cervical cells and has a high success rate in removing abnormal cells. [1]
Potential benefit | What it means |
Removes abnormal tissue | A thin layer of cervical surface tissue is removed. [1] |
Provides a tissue sample | The removed tissue can be tested for abnormal or precancerous cells and, when needed, cancer. [1] |
May treat cervical dysplasia | Removing the abnormal cells often treats the condition. [1] |
Usually brief | The procedure takes about 10 to 20 minutes. [1] |
Uses local anesthesia | General anesthesia is not usually required. [1] |
Potential risk or side effect | What to watch for or discuss |
Infection | Report concerning discharge, fever or other symptoms of infection. [1] |
Bleeding | Heavy bleeding or bleeding with clots needs medical advice. [1] |
Cervical weakening | Discuss future pregnancy concerns because the cervix may be weakened. [1] |
Cramping or aching | Mild cramps and short-lived abdominal or vaginal discomfort can occur. [1] |
Vaginal discharge or spotting | Discharge or spotting may occur for one to three weeks. [1] |
What happens after LEEP?
After the procedure, you may rest in the office for 30 to 60 minutes until you are comfortable enough to leave. During this time, the healthcare professional reviews aftercare instructions and answers questions. [1]
Rest on the day of the procedure. Follow the instructions about activity, vaginal products, bathing, pain relief and follow-up. [1]
Common recovery symptoms
Mild cramps for a few days are common. Greenish-yellow discharge may occur immediately after the procedure and can have an unpleasant smell. Brownish-black discharge can also be normal. Vaginal discharge or spotting may continue for one to three weeks. Pads, rather than tampons, can be used to manage the discharge. [1]
Aching or discomfort in the abdomen or vagina may feel like a scraped knee on the cervix and should last only a short time. The procedure should not change when your next period occurs or how much you bleed. [1]
Figure 3. Recovery includes rest, temporary restrictions, cervical healing and follow-up; warning signs should be discussed with the healthcare team.
LEEP recovery timeline
Time after LEEP | What may happen |
First day | Rest and follow the aftercare instructions. Mild cramps and discharge may occur. [1] |
30–60 minutes after the procedure | Some people remain in the office until comfortable enough to leave while instructions are reviewed. [1] |
One to two days | Many people can return to work or school. [1] |
One to three weeks | Vaginal drainage or spotting may occur. Use pads rather than tampons. [1] |
At least four weeks | Avoid intercourse and inserting tampons or sex toys while the cervix heals, unless your provider gives different instructions. [1] |
Four to six weeks | The cervix generally fully heals in this period. [1] |
What activity and vaginal-care restrictions apply after LEEP?
Avoid excessive activity for 48 hours and restrict exercise for at least one week. If bleeding unrelated to menstruation begins after exercise, stop exercising and allow more time to heal before becoming active again. [1]
Wait at least four weeks before intercourse. Do not insert tampons or sex toys during this healing period. Showering is allowed, but avoid baths and swimming until the healthcare professional says they are safe. [1]
Pain relief during recovery
Mild cramping and bleeding can occur. A non-aspirin pain reliever may be used for discomfort if the healthcare professional recommends it. Use only the medicine and dose provided in your individual instructions. [1]
What happens to the tissue removed during LEEP?
The removed tissue is tested for abnormal or precancerous cells and, when necessary, cancer. LEEP can therefore provide information that a visual examination alone cannot provide. [1]
Removing the tissue often cures cervical dysplasia by eliminating the abnormal cells. Some people need another procedure if the cells were not completely removed or later return. [1]
Does LEEP remove HPV?
No. LEEP removes abnormal cells that formed in response to HPV infection, but it cannot eliminate the virus itself. If high-risk HPV persists, more frequent Pap and HPV testing may be needed to look for infection and new abnormal cell changes. [1]
Follow-up timing and testing depend on the individual findings and the healthcare professional’s plan. Do not skip follow-up because you feel well after the procedure. [1]
Does the cervix grow back after LEEP?
New, healthy tissue grows on the cervix to replace the tissue that was removed. Healing still takes time, and the cervix generally needs four to six weeks to fully heal. [1]
When should you contact a healthcare professional after LEEP?
Contact the healthcare professional during recovery for heavy bleeding greater than a normal menstrual flow, bleeding with clots, vaginal discharge with an increasingly foul odor, fever or severe abdominal pain. [1]
A clinician should also know if pain becomes intense during the procedure or if symptoms are worsening rather than improving. If symptoms seem severe or urgent, use the emergency instructions supplied by the treating team. [1]
How does LEEP affect future pregnancy?
LEEP may weaken the cervix and contribute to preterm birth in future pregnancies. If you are pregnant, planning pregnancy or concerned about fertility, discuss those concerns before the procedure so the healthcare professional can explain how your circumstances affect the plan. [1]
This article does not estimate an individual pregnancy risk. The number, depth and location of tissue samples, prior procedures and other clinical factors require professional assessment. [1]
What questions should you ask before LEEP?
Question | Why it matters |
Why do you recommend LEEP for me? | Clarifies the finding and the purpose of treatment. |
What will happen to the tissue removed? | Explains laboratory testing and when results may be available. |
How might this affect a future pregnancy? | Opens a discussion about cervical healing and preterm-birth concerns. [1] |
What medicines should I take or avoid? | Helps prevent unsafe changes to prescribed medicines. |
How long should I avoid exercise, intercourse, tampons and swimming? | Confirms your individualized restrictions. [1] |
When is follow-up testing needed? | Helps you plan for monitoring after treatment. [1] |
Which symptoms should prompt a call? | Ensures you know how to respond to heavy bleeding, fever or severe pain. [1] |
Conclusion
LEEP is a brief procedure that removes abnormal tissue from the cervix and sends it for testing. It may treat cervical dysplasia while also helping clarify whether the removed cells are precancerous or cancerous. The procedure commonly uses local anesthesia, and the cervix generally heals over four to six weeks. [1]
Before LEEP, ask a qualified healthcare professional why the procedure is recommended, what preparation is needed, how the tissue will be tested, how it may affect a future pregnancy and when follow-up testing is due. Afterward, follow the activity and vaginal-care restrictions and contact the healthcare team for heavy bleeding, clots, increasingly foul-smelling discharge, fever or severe abdominal pain. [1]
Frequently Asked Questions
Is LEEP the same as a biopsy?
LEEP removes a thin layer of abnormal tissue and sends it for testing, so it functions as both a treatment and a diagnostic procedure. It is not described simply as a routine visual examination. [1]
How long does a LEEP procedure take?
The procedure itself takes about 10 to 20 minutes. You may stay for another 30 to 60 minutes afterward until you are comfortable enough to leave and have reviewed aftercare instructions. [1]
Can I return to work after LEEP?
Many people can return to work or school one to two days after the procedure, although recovery differs. Follow the treating team’s instructions and allow more time if symptoms or the procedure require it. [1]
How long will discharge or spotting last?
Vaginal discharge or spotting may continue for one to three weeks. Greenish-yellow discharge immediately after the procedure and brownish-black discharge can occur. Increasingly foul-smelling discharge should be reported. [1]
When can I have sex after LEEP?
Wait at least four weeks before intercourse and avoid tampons or sex toys while the cervix heals. Follow the treating professional’s instructions if they differ. [1]
Can I exercise after LEEP?
Avoid excessive activity for 48 hours and restrict exercise for at least one week. If unrelated bleeding starts after exercise, stop and allow more healing time before resuming activity. [1]
Can I take a bath after LEEP?
You can shower normally, but avoid baths and swimming until the healthcare professional says it is safe. [1]
Does LEEP mean I have cancer?
No. LEEP may be recommended for abnormal cervical cells, and cervical dysplasia is not cancer. The removed tissue is tested to identify abnormal or precancerous cells and, when necessary, cancer. [1]
Can cervical dysplasia return after LEEP?
Cervical dysplasia can. A repeat procedure may be needed if abnormal cells are not completely removed or return. Persistent high-risk HPV increases the risk of recurrence, so follow-up Pap and HPV testing may be recommended. [1]
Will I still have HPV after LEEP?
Yes, it is possible. LEEP removes abnormal cells related to HPV but does not eliminate the virus itself. [1]
What warning signs should I know?
Contact the healthcare professional for heavy bleeding, bleeding with clots, increasingly foul-smelling discharge, fever or severe abdominal pain. [1]
