A vulval biopsy is a minor procedure to remove a small sample of tissue from the vulva (the external genital area) for laboratory testing. It helps diagnose skin changes, infections, or abnormalities such as vulval cancer or pre-cancerous conditions.
This procedure is quick and safe – performed under local anaesthesia (numbing cream or injection) and helps determine the cause of symptomsbut is not a treatment.
Why is it Performed?
Your gynaecologist may recommend this biopsy if you have:
- Unexplained itching, pain, or sores on the vulva.
- Suspicious skin changes (e.g., thickened patches, discoloration, ulcers).
- Concerns about lichen sclerosus, vulval intraepithelial neoplasia (VIN), or cancer.
- Persistent rash or lesions not responding to treatment.
Before the Procedure
- Preparation:
- Avoid blood-thinning medications (e.g., aspirin, ibuprofen) for 24–48 hours (ask your gynaecologist first).
- Shower/wash the vulval area gently.
- Wear loose, comfortable clothing.
- Inform your gynaecologist if:
- You are pregnant or have allergies (e.g., to local anaesthetics).
- You take anticoagulants or have a bleeding disorder.
- Optional: Ask for a female chaperone during the procedure.
During the Procedure
- Positioning: You lie on an exam table with legs supported (similar to a smear test).
- Cleaning: The vulval area is cleaned with an antiseptic.
- Numbing: Local anaesthetic is applied (you may feel a brief sting).
- Biopsy: A small tissue sample is taken using a scalpel or punch tool (takes 5–10 minutes).
- Closure: Stitches may be used for larger samples (dissolvable or removed later).
What you might feel:
- Pressure or mild discomfort (no pain due to anaesthesia).
- Slight tugging during the biopsy.
Risks and Complications
- Common (temporary):
- Mild pain, bruising, or swelling.
- Light bleeding/spotting for 1–2 days.
- Rare but serious:
- Infection (redness, warmth, pus, or fever).
- Allergic reaction to anaesthetic (rash, itching).
- Scarring or changes in skin sensation (rare).
Aftercare
- Wound care:
- Keep the area clean and dry.
- Use a sanitary pad (not tampons) if bleeding.
- Avoid baths, swimming, or tight clothing for 3–5 days.
- Pain relief: Over-the-counter painkillers (e.g., paracetamol).
- Avoid: Sex, vigorous exercise, or scented products until healed (1–2 weeks).
Getting Results
- Results take 1–2 weeks. Your doctor will explain:
- Diagnosis (e.g., infection, inflammation, or pre-cancer).
- Next steps (e.g., medication, further tests, or treatment).
Frequently Asked Questions
Q: Will it hurt?
A: The area is numbed, so discomfort is minimal. You may feel soreness afterward.
Q: How big is the scar?
A: The biopsy site is small and heals into a faint mark (rarely noticeable).
Q: Can I drive home?
A: Yes – no sedation is used.
Q: What if the results show cancer?
A: Your doctor will discuss treatment options (e.g., surgery, radiotherapy).
Q: Can I shave the area before the biopsy?
A: Avoid shaving for 2–3 days prior to reduce infection risk.
eGynaecologist Advice:
- You should seek urgent gynaecological consultation if you notice heavy bleeding, raised temperature >38°C, or severe pelvic pain following the procedure
