Genital warts diagnosis and treatment (Anogenital warts (HPV) diagnosis and treatment)

What is genital warts diagnosis and treatment?

Genital warts are small, often usually not painful lumps that can appear on or around the genitals or anus. They are caused by certain types of the human papillomavirus (HPV), most commonly types 6 and 11. These types are not the ones linked to cancer, so genital warts themselves carry a very low cancer risk.

Warts are usually diagnosed simply by a clinician looking at them, sometimes with a magnifying lens. They are passed on through skin-to-skin contact during sex, and the virus can spread even when there are no visible warts.

Treatment aims to clear the visible warts using creams you apply at home, freezing (cryotherapy), or removal by a clinician. The important thing to understand is that treatment removes the warts but does not remove the virus from the body, so warts can come back after treatment. Many people's bodies clear the virus over time on their own.

NHS sexual health (genitourinary medicine, or GUM) clinics diagnose and treat genital warts free and confidentially, and often get results faster than a GP surgery. The HPV vaccine protects against the main wart-causing types and is offered to young people.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Home cream vs clinic treatments

No single treatment is clearly best, and the choice depends on the number, size and site of warts, pregnancy, and your preference. Recurrence is common with all of them, because treatment does not remove the virus.

Preparing for your treatment

• Note when you first saw the warts and whether they have changed, as this helps the clinician.
• Tell the clinic if you are pregnant or might be, as some treatments (such as podophyllotoxin) are not used in pregnancy.
• Mention where the warts are (including inside the anus or vagina), so the right treatment is chosen.
• Bring a list of medicines and any skin conditions or allergies.
• Ask whether a home cream or a clinic treatment suits your warts best.
• Be ready for treatment to take weeks and possibly several visits.
• You do not need ID or proof of address, and the service is confidential.

What happens

At a clinic, a clinician will ask about your symptoms in confidence and, with your permission, examine the affected area, sometimes using a magnifying lens. Warts are usually diagnosed by their appearance, so tests are not normally needed; a small biopsy is taken only if the diagnosis is uncertain.

You and the clinician then choose a treatment together. You may be given a cream to use at home with instructions, or have the warts frozen in the clinic. Freezing and some other treatments often need to be repeated over several sessions.

Larger or stubborn warts may be removed using heat, laser or minor surgery under local anaesthetic. Throughout, the clinician will explain that treatment clears the warts you can see but does not remove the virus, so warts may return and further treatment is sometimes needed.

Is this treatment right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

The biggest thing to understand is that recurrence is common with every treatment, because treatment clears the warts but not the underlying virus. This is not a sign of treatment failure. Some treatments irritate the skin, and not all are safe in pregnancy, so tell the clinic if you are or might be pregnant. If a lump looks unusual or does not respond, the clinician may take a biopsy to be sure of the diagnosis.

Published figures to discuss

How well genital warts respond, and whether they come back, varies a great deal between people and treatments, so single figures can mislead. No treatment clears warts in everyone, and recurrence is common with all of them because the virus remains. Around half of episodes are recurrences. Clearance depends partly on the immune system, which controls the virus over time in most people, so outcomes reflect biology and the warts' size and site rather than test accuracy.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no major recovery from diagnosis or most treatments. Skin may be sore for a few days after creams or freezing. Clearing warts often takes weeks and several sessions, and they can return, so patience is part of the process.

• Sore, red or itchy skin for a few days after creams or freezing
• Needing several treatment sessions before warts clear
• Some warts responding faster than others
• Warts returning after treatment, which is common and not a sign of failure
• Feeling self-conscious at first, which usually eases with information

Aftercare

• Use creams exactly as directed, including how long to leave them on and when to wash them off.
• Expect some soreness or redness after treatment, and keep the area clean and dry.
• Avoid sex while the skin is sore from treatment, and be aware the virus can spread even without visible warts.
• Tell partners; condoms reduce but do not remove the risk of passing HPV on.
• Do not use wart treatments meant for hands or feet on the genitals.
• Tell the clinic if you are or become pregnant, as treatment choices change.
• Return if warts spread, do not respond, or look different from before.
• Ask about the HPV vaccine if you have not had it.

• Clear written instructions for any home cream
• Knowing how many clinic sessions to expect
• A plan to avoid sex while treated skin is sore
• A note of pregnancy status, as it affects treatment
• The clinic's contact number saved for questions
• Awareness that recurrence is common and not a failure
• A reminder to ask about the HPV vaccine

⚠ Get urgent help if…

• A lump that bleeds, hardens, ulcerates or looks different from the other warts
• Rapidly spreading or very large warts
• Severe pain, swelling, pus or fever after a treatment (possible infection)
• Warts that do not respond at all to treatment
• New warts appearing during pregnancy, which need specific advice
• A weakened immune system with widespread or stubborn warts

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

Successful treatment means the visible warts have cleared, which often takes weeks and sometimes several courses. Because treatment does not remove the virus, clearance does not guarantee warts will not come back, and about half of people treated have a recurrence.

A good outcome also includes understanding the diagnosis: that wart-causing HPV types carry a very low cancer risk, that many people clear the virus naturally over time, and that recurrence is not a sign of having done anything wrong. If a lump looks unusual, a biopsy confirms it is a harmless wart.

Clearing the visible warts does not clear the virus, so warts can return for a time after treatment. For most people, the immune system controls or clears the virus over months to a couple of years, after which recurrences become less likely. There is no test that confirms the virus has gone, so management is based on whether warts are present rather than on a virus test.

Related tests, treatments or support

Genital warts are diagnosed and treated alongside general sexual health care, and the clinic will usually offer tests for other infections such as chlamydia, gonorrhoea, HIV and syphilis, as they share similar risks. The HPV vaccine may be discussed, as it protects against the main wart-causing types and some cancer-causing types.

Follow-up & long-term care

You may be reviewed during treatment to check progress and decide whether to continue or switch methods. There is no routine test of cure, because the aim is to clear visible warts rather than the virus. Come back if warts return, do not respond, look unusual, or if you become pregnant, as treatment choices change.

• Repeat or switch treatment if warts return or do not respond.
• The HPV vaccine to help protect against the main wart-causing types.
• Condoms to reduce, though not remove, the chance of passing HPV on.
• General health measures, as a strong immune system helps control the virus.

Repeat, follow-on and what comes next

• Several treatment sessions are often needed before warts clear.
• If one treatment does not work, another (for example switching from a cream to freezing) is tried.
• Warts can recur after clearance and may need a further course; there is no test of cure for the virus.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• Clear advice that treatment clears warts but not the virus, and that recurrence is common.
• Written instructions for home treatments and a plan for clinic sessions.
• A named contact and review if warts return, do not respond, or look unusual.
• Advice on the HPV vaccine, reducing spread, and pregnancy-specific care where relevant.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• Whether you use the free NHS service or pay privately
• Whether treatment is a home cream or clinic-based (freezing, heat, laser or surgery)
• The number of treatment sessions needed
• The number, size and site of the warts
• Whether a follow-up review is included
• Whether you also test for other infections at the same time

• The cost of the consultation and diagnosis
• Which treatment is included and how many sessions are covered
• Whether repeat treatment is covered if warts return
• Whether a follow-up review is included
• What happens, and what it costs, if a biopsy is needed
• Whether testing for other infections and HPV vaccine advice are included

On the NHS? Genital warts are diagnosed and treated free and confidentially on the NHS at sexual health (GUM) clinics, often with faster results than a GP; private treatment is an option but is not more effective, and recurrence is common whoever treats them.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the specialist is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
