Cervical dysplasia means abnormal cells on the surface of the cervix. It is not cancer. Laboratories report it as CIN 1, 2 or 3, or as low-grade and high-grade lesions (LSIL and HSIL).
Low-grade changes usually clear without treatment within one to two years. High-grade changes can progress to cancer over many years if left, and removing them is simple and highly effective, which is the whole purpose of cervical screening.
Symptoms
- No symptoms in nearly all cases, which is why screening matters
- An abnormal smear or a positive high-risk HPV test
- Bleeding after sex or between periods is not typical of dysplasia and needs examination in its own right
Causes and risk factors
Almost all cervical dysplasia is caused by persistent infection with high-risk types of human papillomavirus, particularly types 16 and 18. HPV is extremely common and most infections are cleared by the immune system within two years. Persistence is more likely with smoking, a weakened immune system (HIV, transplant medicines, long-term steroids) and possibly long-term use of the contraceptive pill. Having HPV says nothing about faithfulness, as the virus can lie dormant for years.
How it is diagnosed
- HPV test and cervical cytology: The screening tests that flag who needs a closer look.
- Colposcopy: The cervix is examined under magnification after applying dilute acetic acid and iodine to highlight abnormal areas.
- Directed biopsy: Small samples from abnormal areas give the CIN grade.
- Endocervical sampling: Used when the abnormal area extends into the canal and cannot be fully seen.
Treatment options
- Observation: CIN 1, and CIN 2 in some younger women who wish to have children, are rechecked at 6 to 12 month intervals since many regress.
- LEEP or LLETZ: A thin wire loop removes the abnormal zone under local anaesthetic in about 15 minutes. It is the standard treatment for CIN 2 and 3.
- Cone biopsy: A slightly larger removal, by scalpel or laser, for disease in the canal or suspected glandular abnormality.
- Ablation: Freezing or thermal treatment destroys tissue without providing a specimen, used in selected cases.
- Follow-up test of cure: An HPV test at about six months. HPV vaccination around the time of treatment may reduce recurrence.
When it is urgent
Heavy bleeding that soaks a pad within an hour, fever, foul discharge or severe pelvic pain after a loop procedure need same-day medical attention locally. Persistent bleeding after sex with no screening history should be examined promptly.
Travelling to Türkiye for treatment
Colposcopy with biopsy can be done in a single appointment and LEEP on a second day once results return, so a visit of about a week works. After LEEP, avoid swimming, tampons and intercourse for around four weeks, and plan the flight for a few days after treatment in case of bleeding. The test of cure at six months and routine screening afterwards should be done at home. Bring your smear and HPV reports.
Send your reports, scans and a short history and a Clinic-Y coordinator replies within 24 hours with suitable teams and written, all-inclusive proposals side by side. Reviewing your case is free.
Frequently Asked Questions
Does treatment affect future pregnancy?
A single shallow loop has little effect. Deeper or repeated excisions slightly raise the risk of preterm birth, which is why mild changes are watched rather than treated.
Will the HPV go away?
In most women the virus becomes undetectable after treatment, though not always.
Should my partner be tested?
There is no approved routine HPV test for men, and treatment of partners is not needed.
Is CIN 3 cancer?
No. It is the most advanced pre-cancer stage and is confined to the surface layer.
