The short answer: A colposcopy is a close, magnified look at the cervix, done in the clinic in much the same position as a Pap smear. If an area looks abnormal, a tiny piece of tissue (a biopsy) is taken. A LEEP (also called LLETZ) removes the abnormal area with a thin wire loop, usually under local anaesthetic; a cone biopsy removes a slightly larger, cone-shaped piece. These procedures treat precancerous changes (CIN) so that they do not become cancer. Being sent for colposcopy does not mean you have cancer; only the biopsy result can confirm or rule it out.
In Hindi this is often searched as colposcopy kya hota hai (कोल्पोस्कोपी क्या होता है), usually alongside worry about bachedani ke muh ka cancer (बच्चेदानी के मुँह का कैंसर). If you are still trying to understand your result, start with what CIN 1, 2 or 3 means or what a positive HPV test means.

LEEP, Cone Biopsy and Colposcopy: Treating Cervical Precancer
The path from an abnormal cervical smear to a definite answer from the tissue (histology) and treatment — when needed — is now straightforward, highly effective, and in most cases completed in the outpatient clinic. Understanding what each procedure involves helps women approach these appointments with confidence rather than anxiety. Our checklist on preparing for a specialist appointment lists what to bring, including earlier Pap, HPV and biopsy reports.
Colposcopy: The Diagnostic Foundation
Colposcopy is the first step after any high-grade smear result or positive HPV with abnormal cytology. The colposcopist examines the cervix under magnification after applying dilute acetic acid and Lugol iodine solution. Areas that turn white after the solution (acetowhite) or show unusual patterns of tiny blood vessels (mosaic or punctation) suggest where higher-grade changes may be. Targeted biopsies are taken from the most abnormal-looking areas, and the results determine whether treatment is needed. For what these changes are, see understanding precancerous cervical changes.
What it feels like: you lie as you would for a Pap smear, a speculum is placed, and the doctor looks through the colposcope, a magnifier that stays outside the body. Most women feel only mild discomfort; a biopsy can feel like a brief pinch or cramp. You can usually go home straight afterwards, and light spotting or a dark discharge for a few days is common. The biopsy result usually leads to one of three paths: no treatment and a repeat test later, treatment of the abnormal area, or, rarely, further tests if cancer is suspected.
LEEP/LLETZ: The Standard Treatment for High-Grade CIN
Large loop excision of the transformation zone (LLETZ in the UK, LEEP in North America) uses a wire loop energised with electrical current to excise the entire transformation zone under local anaesthetic. The procedure takes 10–20 minutes. Recovery involves a few weeks of light discharge and avoiding intercourse and tampons. The excised specimen provides definitive histology — confirming the grade of CIN and whether margins are clear. Cure rates for CIN 3 with a single LLETZ are 90–95%. If you may want a pregnancy in future, ask about this before treatment: a LEEP removes only a small piece of tissue, but larger or repeated treatments can slightly raise the chance of an early (preterm) birth, so the amount removed is kept as small as safely possible.
Cone Biopsy: When More Tissue Is Needed
A cone biopsy removes a cone-shaped section of the cervix under general or spinal anaesthesia. It is used when: the lesion extends into the endocervical canal beyond the reach of LLETZ; when glandular abnormalities (CGIN/AIS) are present; or when early invasive disease needs to be excluded with clear deep margins. The procedure slightly increases the risk of cervical incompetence (a weakened cervix that can open too early) in later pregnancies — an important consideration for women who have not yet completed their family.
After Treatment: Surveillance Matters
Treatment is not a discharge point — it is the beginning of a surveillance programme. Test-of-cure co-testing at 6 months distinguishes women who are HPV-negative (low risk, return to routine screening) from those who are HPV-positive (higher risk, annual surveillance for 3–5 years). Persistent HPV after two treatments warrants discussion about further management options including hysterectomy in women who have completed their family.
