Colposcopy and LLETZ: What to Expect, Recovery and Future Pregnancy

Key message: Colposcopy is a closer examination of the cervix after an abnormal screening result or concerning appearance. Referral does not mean cancer. A biopsy or LLETZ may be used to diagnose or remove precancerous cells.
Get urgent help: After biopsy or LLETZ, seek urgent advice for bleeding heavier than a heavy period or soaking pads rapidly, fever, offensive discharge, severe or increasing lower-abdominal pain, faintness or feeling very unwell.
Why is colposcopy offered?
- High-risk HPV with abnormal cervical cells.
- Persistent HPV or follow-up after treatment according to the screening pathway.
- An abnormal-looking cervix or symptoms requiring direct assessment.
- An inadequate or unusual screening result in selected cases.
What happens during colposcopy?
A speculum is inserted as for cervical screening. The colposcope remains outside the body while diluted acetic acid and sometimes iodine are applied to the cervix.
The clinician documents the transformation zone and may take a small biopsy. You can ask to pause or stop at any time.
What is LLETZ?
Large-loop excision of the transformation zone uses a thin heated wire loop to remove abnormal tissue, commonly with local anaesthetic in an outpatient setting. The tissue is sent to pathology.
Treatment may occur at the first visit or after biopsy results, depending on the appearance, grade and pathway.
What pain or bleeding is expected?
A biopsy can cause a short pinch or cramp and light bleeding. LLETZ can cause period-like discomfort and watery, brown or blood-stained discharge for up to several weeks.
Pain should improve and bleeding should not be heavier than a heavy period.
What aftercare is advised?
- Use pads rather than tampons or menstrual cups while bleeding/discharge continues.
- Avoid penetrative vaginal sex for the interval advised, often around 4 weeks after LLETZ.
- Avoid swimming and strenuous exercise for the period recommended by the treating service.
- Follow hygiene advice and do not use vaginal douches.
- Keep the result and follow-up appointment.
What are the possible risks?
- Bleeding or infection.
- Incomplete removal or recurrent cell changes.
- Cervical narrowing rarely.
- A small increase in later preterm-birth risk, particularly after deeper or repeated excisions.
- Anxiety or pain requiring tailored support or another anaesthesia plan.
What happens to the pathology result?
The report confirms the grade, whether the abnormal area appears removed and whether any unexpected diagnosis is present. The service should explain the result and next step rather than relying on the patient to interpret a portal entry.
Further treatment is uncommon but may be needed for incomplete excision, glandular changes or suspected cancer.
What is test of cure?
A follow-up HPV-based cervical test is commonly performed after treatment—often at about 6 months in NHS pathways. The exact interval should follow the current national or local cervical-screening follow-up programme.
A negative result usually returns the patient to an appropriate recall pathway; positive results may require repeat colposcopy.
What if I am pregnant or want pregnancy later?
Colposcopy and selected biopsy can be performed in pregnancy when needed, while treatment is usually delayed unless cancer is suspected. Tell the colposcopy team about pregnancy before the procedure.
In a future pregnancy, report previous LLETZ, cone biopsy and procedure depth because cervical-length surveillance may be considered.
Frequently asked questions
Does referral mean cancer?
No. Most referrals involve HPV or precancerous changes, not cancer.
Can I drive home?
Usually after diagnostic colposcopy or local-anaesthetic LLETZ if you feel well, but follow the service advice.
How long will discharge last?
It can continue for several weeks after LLETZ and should gradually improve.
Will LLETZ affect fertility?
It does not usually prevent conception, but deeper or repeated excision can slightly increase preterm-birth risk.
Do I still need screening after treatment?
Yes. Test-of-cure and later screening are essential.
Your next step
Keep the pathology and follow-up plan. Seek care for heavy bleeding, fever, offensive discharge or worsening pain, and tell the maternity team about previous cervical excision in a future pregnancy.
