LEEP Procedure: What to Expect Before, During and After Recovery
A LEEP (loop electrosurgical excision procedure) removes abnormal, precancerous cells from the cervix using a thin wire loop that carries an electric current. It's usually done in a gynecologist's office with local numbing and takes about 10 to 20 minutes. LEEP is very effective at preventing cervical cancer, and most people are back to normal activities within a day or two.
If you've just been told you need one, the word "electrosurgical" probably didn't help. In real life, most people describe it as a few uncomfortable minutes, a weird smell, and a couple of weeks of annoying discharge. Here's the full picture, start to finish.
Why you might need a LEEP
Doctors most often recommend a LEEP when a colposcopy biopsy shows:
- CIN 2 or CIN 3 (moderate to severe precancer), also called HSIL
- Ongoing CIN 1 in some situations
- Results that don't match, such as an HSIL Pap with a less severe biopsy
For some adults 25 and older who aren't pregnant and have an HSIL Pap with HPV 16, guidelines allow LEEP without a prior biopsy. This is called expedited treatment.
LEEP both treats and diagnoses. The removed tissue goes to a lab, which confirms how severe the changes were and whether the edges (margins) are clear.
LEEP vs. other cervical treatments
| Procedure | How it works | Where it's done | Tissue sent to lab? |
|---|---|---|---|
| LEEP | Electric wire loop removes tissue | Office, local anesthetic | Yes |
| Cold-knife cone biopsy | Scalpel removes a cone of tissue | Operating room, anesthesia | Yes |
| Cryotherapy | Freezes abnormal cells | Office | No |
| Thermal ablation | Heat destroys abnormal cells | Office | No |
Your clinician chooses based on the size and location of the abnormal area, the type of cells and whether a tissue sample is needed. Glandular precancer (AIS) usually needs an excision, often a cone biopsy.
The week before: prep checklist
- Schedule outside heavy period days if you can.
- Tell your clinician if you might be pregnant, take blood thinners or have a bleeding disorder.
- Ask about pain relief. Some clinicians suggest an over-the-counter pain reliever beforehand. Don't take anything without asking.
- Skip sex, tampons and vaginal products for a day or two before, if instructed.
- Arrange a ride if you'll get sedation. Most office LEEPs use only local anesthetic, so many people take the train home, but a car is nicer if you have a long commute.
- Buy pads (not tampons) for the weeks after. You'll want a stash.
The procedure, step by step
- You lie on the exam table like you would for a Pap test. A sticky grounding pad goes on your thigh. That's a safety feature for the electric current, not something you'll feel.
- A speculum holds the vagina open.
- The cervix is stained with a vinegar or iodine solution to outline abnormal areas. It might sting a little.
- Local anesthetic is injected into the cervix. You may feel a pinch, and if it contains epinephrine, a brief racing heartbeat. That's expected and passes in a minute or two.
- The wire loop passes across the cervix in a few seconds, removing a thin piece of tissue.
- The area is sealed with heat or a paste to control bleeding.
You may hear a buzzing sound, notice a burning smell from the device (yes, everyone notices; there's a smoke evacuator for it), and feel cramping or pressure. The actual removal takes only seconds. Most people say the numbing shot was the worst part.
Recovery: week by week
Day 1 to 3. Most people feel well enough for work or school the next day. Expect mild cramping and watery discharge.
Week 1 to 2. It's normal to have:
- Watery, pink or brown discharge
- Dark, coffee-ground-like discharge from the bleeding-control paste. It looks alarming and is completely expected.
- Light spotting, sometimes a bit heavier around a week after as the scab comes off
Week 2 to 4. Discharge tapers off. You're still healing on the inside even if you feel fine.
What to avoid while you heal
Follow the exact instructions you get at discharge. They often include avoiding these for about four weeks:
- Vaginal sex
- Tampons and menstrual cups
- Douching
- Baths, swimming pools and hot tubs (showers are fine)
- Heavy lifting or intense exercise for the first several days
A common question is whether a period during that window is a problem. It isn't; just use pads.
Risks, honestly
This is a common and generally safe procedure. Possible risks include:
- Bleeding, during the procedure or in the first couple of weeks
- Infection, which may cause fever, pain or foul-smelling discharge
- Cervical stenosis, a narrowing of the cervical opening that can occasionally cause painful or missed periods
- Positive margins, meaning abnormal cells reached the edge of the removed tissue. This doesn't always mean more surgery, but it may mean closer follow-up.
- Recurrence, since precancer can return, which is why follow-up testing matters
Serious complications are uncommon. Your clinician will review your specific risks beforehand.
LEEP and future pregnancy
LEEP doesn't usually make it harder to get pregnant. But removing part of the cervix can slightly increase the risk of preterm birth in a later pregnancy, and the risk tends to be higher with deeper or repeated procedures.
If you've had a LEEP, tell your prenatal provider at your first visit. They may check the length of your cervix during pregnancy. If you're planning pregnancy soon and have CIN 2, ask whether observation is a safe option for you.
Does LEEP get rid of HPV?
LEEP removes the abnormal cells, not the virus. Many people test HPV-negative afterward because the infected tissue is gone and the immune system clears the rest. Some don't, which is one reason follow-up matters.
Your follow-up schedule
Precancer can come back, so ASCCP guidelines generally recommend:
- An HPV-based test about 6 months after treatment
- Then yearly testing until you have three negative results in a row
- Then testing every 3 years for at least 25 years, even if that goes past age 65
Expect adjustments based on your results and margins. Set a phone reminder for the 6-month test before you leave the office. That one is the easiest to forget, because by then you'll feel completely normal.
Cost and coverage in New York
The procedure is a covered diagnostic and treatment procedure under NY Medicaid, the Essential Plan and most private plans. If you're uninsured, New York's Cancer Services Program covers cervical diagnostic follow-up for people who qualify; ask the office or your local program.
When to call your provider
Call right away if you have:
- Heavy bleeding, especially soaking a pad in an hour, or bleeding heavier than a period
- Fever or chills
- Severe abdominal pain not relieved by usual measures
- Foul-smelling discharge
If the lab finds cancer in the LEEP specimen, you'll be referred to a gynecologic oncologist. For background, see what is a colposcopy and abnormal Pap smear results. To find a gynecologist near you, search the directory.
Frequently asked questions
What is a LEEP procedure?
LEEP stands for loop electrosurgical excision procedure. A thin wire loop with an electric current removes a small piece of the cervix containing abnormal precancerous cells.
Is LEEP painful?
LEEP is usually done with local anesthetic in the office. Most people feel pressure or cramping rather than sharp pain.
How long does it take to recover from LEEP?
Most people return to daily activities within a day or two. The cervix takes several weeks to heal, so you will be asked to avoid sex and tampons for a period your clinician sets, often around four weeks.
Can you get pregnant after a LEEP?
Yes. LEEP does not usually affect the ability to get pregnant, but it can slightly raise the risk of preterm birth in a later pregnancy, so tell your prenatal provider about it.
Does LEEP remove HPV?
LEEP removes abnormal cells, not the virus itself. Many people clear HPV after treatment, but follow-up testing is still needed.
