The short explanation
CIN 3 means severe cell changes, and treatment is usually recommended because these changes are more likely to progress over time. LEEP removes the affected area with a thin heated wire loop, usually under local anaesthetic, and most women go home the same day. For most women, LEEP does not affect the ability to get pregnant. It can slightly increase the chance of an early delivery in a future pregnancy, especially if a larger piece of tissue is removed or the procedure is repeated. Clinicians weigh this against the risk of leaving CIN 3 untreated, which is the more serious concern.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Your doctor can tell you how much tissue they expect to remove, which helps estimate any effect on pregnancy.
- Clinicians often suggest waiting a few months after LEEP before trying to conceive, to allow healing, and attending the follow-up test. When you do become pregnant, tell your antenatal team about the procedure so they can monitor you.
- Delaying treatment to conceive first is generally not advised for CIN 3. Talk to your doctor openly about your plans.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what effect, if any, the procedure will have on your future pregnancy. Your gynaecologist can explain that based on your findings.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How much tissue do you expect to remove?
- How long should we wait before trying to conceive?
- Will I need extra checks in a future pregnancy?
- What follow-up tests will I need after LEEP?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have very heavy vaginal bleeding, soaking through pads quickly, or bleeding with fainting, severe pain or breathlessness.
Get help the same day
- Get care the same day if you have heavy bleeding, fever or bad-smelling discharge after the procedure.
Raise it at a routine appointment
- Keep your post-treatment check and tell your antenatal clinic about the LEEP when you become pregnant.
