Sampling of small tissue from the cervix for laboratory examination of cellular changes. Performed for diagnostic purposes after abnormal smear or HPV-positive results.
Indication
- Abnormal smear result (LSIL, HSIL, ASC-H, AGC)
- High-risk HPV positivity (especially HPV 16/18)
- Suspicious cervical lesion seen on colposcopy
- Visible mass, ulcer, or contact bleeding on the cervical surface
- Post-treatment follow-up (after LEEP/conization)
- Postmenopausal abnormal bleeding
Preparation
- Scheduled within 1-2 weeks after the menstrual period ends
- Avoid vaginal medications, intercourse, and douching for 24 hours before the procedure
- If using blood thinners, evaluate temporary discontinuation with the physician
- If pregnancy is suspected a test is performed; the method may change in active pregnancy
- Taking a mild pain reliever before the procedure may be soothing
How it's performed
- Patient is placed in the gynecologic examination position and a speculum is inserted
- Cervix is examined in detail with a colposcope (magnifying device)
- Suspicious areas are highlighted with acetic acid and Lugol's solution
- A small piece of tissue is taken from the suspicious area with punch biopsy forceps
- If a wider sample is needed, LEEP (loop electrosurgical excision) or conization is performed
- Bleeding is controlled with Monsel's solution or cautery; tissue is sent to pathology
Post-procedure
- Mild spotting and watery discharge are normal for 1-2 weeks after the procedure
- Avoid intercourse, tampons, vaginal douching, and swimming pools for 2-4 weeks
- Pathology results are usually ready in 5-10 business days
- Follow-up examination or additional treatment (LEEP, conization) plan based on results
- Seek immediate care if fever, severe pain, or active bleeding occurs
Risks
- Mild to moderate bleeding (more common with LEEP/conization)
- Infection (rare; 1-2%)
- Cervical stenosis (especially after repeated conization)
- Slight increase in cervical insufficiency or preterm birth risk in subsequent pregnancies
- Insufficient tissue sample requiring repeat procedure
FAQ
Is cervical biopsy painful?
Brief cramp-like pain may be felt during punch biopsy. For wider procedures such as LEEP, local anesthesia is applied and pain is generally mild.
Does an abnormal smear always mean cancer?
No. Most abnormal smear results indicate precancerous changes (CIN1-2-3); with early intervention progression to cancer can be prevented.
Can I become pregnant after a biopsy?
Yes. Punch biopsy does not affect fertility. Pregnancies after conization and LEEP are followed somewhat more closely.
When are the results available?
Pathology results are usually ready within 5-10 business days. Additional immunohistochemistry studies may extend this period when needed.
