Warts and Wart Removal: What You Should Know Before Treating Them

A small rough bump on the hand, foot, or another part of the body may be a wart, but not every skin growth is. Warts are caused by certain types of human papillomavirus (HPV), and they can spread from one area of skin to another or from one person to another.

Most warts are harmless and may eventually disappear without treatment. Still, some remain for a long time, become painful, spread, or cause concern about how they look. Knowing what you are dealing with is the first step before deciding how to remove it.

What is a wart?

A wart is a non-cancerous skin growth caused by certain types of HPV. The virus enters the skin through small cuts, cracks, or other breaks and causes the outer layer of skin to grow more quickly.

Warts can look different depending on where they appear. A typical wart may feel rough and raised, while others are flatter and smoother. Warts on the soles of the feet can become thick and painful because pressure from walking pushes them deeper into the skin.

The appearance of a wart can sometimes overlap with other skin lesions. That is one reason it is not a good idea to assume that every unusual bump is a wart.

Why do warts develop, and are they contagious?

Yes, warts are contagious.

The HPV types that cause ordinary skin warts can spread through direct skin contact or through contaminated objects and surfaces. The virus is more likely to enter through damaged skin. Picking, scratching, or shaving over a wart can also move the virus to nearby areas.

This does not mean that every person who touches a wart will develop one. The immune response to HPV differs from person to person.

Some simple precautions can reduce the chance of spreading warts:

• Do not pick or scratch them.
• Wash your hands after touching or treating a wart.
• Avoid sharing towels, razors, socks, shoes, or personal items that come into contact with the affected area.
• Avoid shaving directly over a wart.
• Keep a wart covered when appropriate, particularly if it is being irritated or is likely to come into contact with other people's skin.

What are the different types of warts?

Several types can appear on the skin.

Common warts are usually rough, raised growths found on the hands, fingers, and around the nails. They may contain tiny dark dots, which are small blood vessels within the wart.

Plantar warts occur on the soles of the feet, particularly around the heels and balls of the feet. They may have a thick layer of hard skin over them and can hurt when walking or standing.

Flat warts are smaller and smoother than many other warts. They can occur on the face, legs, and other areas and are more common in children and young people.

Filiform warts are thin, thread-like growths that often appear around the face, mouth, or nose.

Genital warts are different from ordinary hand or foot warts. They occur around the genital or anal area and are associated with specific types of HPV. Over-the-counter wart removers intended for hands or feet should not be used on genital skin.

Do warts go away on their own?

They can.

Many warts eventually disappear without treatment, particularly in children and people with a healthy immune system. The problem is that there is no reliable way to predict exactly when an individual wart will disappear.

Some may remain for months or even years. Others may spread or become troublesome before they clear.

Treatment is therefore not always necessary simply because a wart exists. The decision can depend on its location, size, number, symptoms, duration, and how much it bothers the person.

How are warts treated or removed?

There is no single treatment that works for every wart. A dermatologist may choose an approach based on the type and location of the wart, the patient's age and health, and previous treatment.

Salicylic acid

Salicylic acid is one of the commonly used treatments for ordinary and plantar warts. It gradually removes layers of the wart and is available in different preparations.

It usually requires regular application rather than a single treatment. The surrounding skin can become irritated, especially if the medication is applied beyond the wart.

Cryotherapy

Cryotherapy involves freezing the wart, usually with liquid nitrogen. The freezing damages the wart tissue, which then gradually forms a blister or crust and clears.

The procedure can sting or hurt, and temporary blistering, soreness, changes in skin colour, or scarring can occur. More than one treatment may be needed.

Other treatments

Warts that do not respond to standard treatment may sometimes be treated with other methods, such as prescription medicines, cantharidin, electrosurgery, curettage, laser treatment, or immune-based treatments.

These are not appropriate for every wart. A dermatologist can decide whether one of these approaches makes sense after examining the lesion.

Does wart removal hurt?

It depends on the treatment and the location of the wart.

Salicylic acid may cause stinging or irritation. Cryotherapy can be uncomfortable during freezing and may leave the area sore or blistered afterwards. Procedures that remove or destroy wart tissue may require local anaesthesia.

A plantar wart can also be more uncomfortable to treat because the sole of the foot is exposed to pressure while walking.

The important point is that "wart removal" does not automatically mean a completely painless procedure. The expected discomfort and aftercare should be discussed before treatment.

Can you remove a wart at home?

Some ordinary hand or foot warts can be treated at home with commercially available salicylic-acid products. They need to be used carefully and consistently according to the product instructions.

Home treatment is not appropriate for every situation. People with diabetes, poor circulation, or reduced sensation in the area should speak with a healthcare professional before using salicylic acid or attempting to remove a wart themselves.

Avoid cutting, burning, or digging out a wart yourself. These methods can injure healthy skin, cause infection or scarring, and potentially help the virus spread to nearby skin.

Do not use ordinary wart-removal products on the face or genital area without medical advice. Genital warts require different treatment, and other skin conditions can sometimes look similar to a wart.

Can warts come back after treatment?

Yes.

Treatment removes or destroys the visible wart, but it does not necessarily eliminate HPV from the surrounding skin. A wart can therefore return after treatment. A new wart may also develop elsewhere if the virus spreads to another area.

Recurrence does not automatically mean that the treatment was performed incorrectly. Some warts are simply persistent or difficult to clear.

When should you see a dermatologist?

A dermatologist can be particularly helpful when you are not sure that a growth is actually a wart.

Medical assessment is sensible if the lesion:

• Changes in appearance
• Bleeds, burns, itches, or becomes painful
• Keeps growing or spreading
• Appears on the face or genital area
• Is present in large numbers
• Interferes with walking or normal activities
• Has not improved despite appropriate home treatment
• Keeps returning after treatment
• Looks unusual or unlike a typical wart

People with diabetes or a weakened immune system should also seek medical advice rather than repeatedly treating suspicious lesions themselves.

Common misconceptions about warts

"Warts are caused by poor hygiene."
Not necessarily. Warts are caused by HPV. The virus can infect healthy people and enter through very small breaks in the skin.

"A wart has to be removed immediately."
Not always. Many warts are harmless and eventually clear on their own.

"Cutting the wart off is the quickest solution."
Trying to cut one out yourself can damage the surrounding skin and increase the risk of bleeding, infection, scarring, and spreading the virus.

"Once a wart is removed, it can never return."
Unfortunately, recurrence can happen.

"Every rough skin bump is a wart."
No. Corns, calluses, molluscum, seborrhoeic keratoses, and other skin lesions can sometimes be mistaken for warts. When the diagnosis is uncertain, examination by a dermatologist is safer than experimenting with treatments.

For most people, a wart is more of a nuisance than a serious health problem. The main questions are whether it really is a wart, whether it is causing problems, and whether treatment is worth pursuing. When treatment is needed, the safest option is usually the one chosen after considering the particular wart rather than simply using the strongest available removal method.
