wart risks and benefits for patients

Overview

A wart is a small, rough growth on the skin caused by a common virus called human papillomavirus (HPV). Warts are not dangerous and usually go away on their own, but they can be bothersome or spread to other parts of the body.

Yes. Warts are very common and affect people of all ages, though they happen most often in children and teens.

Anyone can get warts, but they are more likely to appear in people who have cuts or scrapes on their skin, people who use public pools or showers, and people with weaker immune systems.

Symptoms

Common symptoms

• Small, raised, rough bumps on the skin
• Flesh-colored, white, pink, or tan lumps
• Black pinpoints inside the wart (these are tiny blood vessels)
• Warts can appear on hands, fingers, feet, knees, or face

Symptoms in children

• Warts in children often appear on the hands and fingers
• They may pick at warts, which can spread the virus to other areas
• Children's warts often go away faster than adult warts

Symptoms in older adults

• Warts are less common in older adults but can still appear
• Older adults may have more skin conditions that look like warts, so a checkup is helpful
• Warts in older adults can sometimes take longer to clear

Causes

Main causes

• Warts are caused by certain types of HPV (human papillomavirus)
• The virus enters the skin through tiny cuts, scratches, or damage
• It makes the top layer of skin grow quickly, creating a wart

Risk factors

• Having direct contact with a wart on someone else
• Walking barefoot in warm, damp places like public pools or locker rooms
• Sharing towels, razors, or other personal items with someone who has warts
• Biting your nails or picking at hangnails, which opens the skin

When to see a doctor

See a doctor urgently if:

• If the wart bleeds heavily, shows signs of infection, or grows very quickly
• If you have a weakened immune system and a wart spreads rapidly

Book a routine appointment if:

• If the wart is painful or in a spot that makes it hard to walk or use your hands
• If you are bothered by how the wart looks
• If a wart comes back after treatment or you are not sure it is a wart
• If you have diabetes and get a wart on your foot, because any foot problem needs extra care

Diagnosis

A doctor usually diagnoses a wart just by looking at it. They may use a small magnifying tool called a dermatoscope to see the tiny black dots (tiny blood vessels) that are typical of warts.

Tests that may be done

• No special test is usually needed
• A skin scraping test may be done if the doctor is not sure
• A biopsy (taking a tiny sample of the skin) is very rare and only done when a wart looks unusual

What to expect at your appointment

The doctor will examine the wart and ask how long you have had it. They may tell you it is fine to leave it alone, or they may offer treatment. The exam is quick and usually painless.

Treatment

Treatment for warts is not always necessary, because many warts go away by themselves. If treatment is chosen, it aims to remove the wart and help your immune system fight the virus. No single treatment works perfectly for everyone.

Self-care at home

• Wash your hands after touching a wart
• Cover it with a bandage to reduce spreading
• Avoid picking, scraping, or biting the wart
• Use topical wart treatments from a pharmacy, following the instructions carefully
• For warts on your feet, keep the area clean and dry and change socks daily

Medical treatments

A doctor or dermatologist may offer several approaches. These include applying a stronger acid or medication to the wart, freezing it with a cryotherapy device to destroy the wart tissue, using a small electric current or laser to remove the wart, or applying a treatment that stimulates your immune system to attack the virus. The choice depends on the size, location, and how long the wart has been present.

When is surgery considered?

Surgery is rarely needed for warts. It may be considered when a wart is very large, deep, or has not responded to other treatments. Minor surgical removal can be done in a doctor's office and leaves a small wound that heals over time.

Living with this condition

Most people with warts live normally without any special routines. If you have a wart, simply try to keep the area clean and covered to avoid spreading the virus to others or to other parts of your body.

Lifestyle tips

• Do not share towels, socks, shoes, or razors
• Wear flip-flops or water shoes in public pools and locker rooms
• Try to keep your immune system strong with regular sleep and balanced meals
• Be patient, because warts can take months to disappear

Diet and exercise

There is no specific diet or exercise that treats warts, but a healthy lifestyle supports your immune system, which is the real key to removing wart-causing viruses.

Mental health and emotional wellbeing

Warts can sometimes make people feel self-conscious, especially when they are on visible areas like hands or face. It can help to remember that warts are very common and not dirty, and you can still go about your daily life as usual.

Prevention

Not completely, but you can lower your chances of getting warts. Avoid direct skin contact with someone who has a wart, keep your feet dry, wear shoes in public places, and do not bite your nails or hangnails.

Vaccines

The HPV vaccine protects against certain types of HPV, including some that cause warts and some that cause cancer. The vaccine is usually given to teenagers, but if you are older, ask your healthcare provider about it.

Screening programmes

There is no routine screening for warts. You only need to check your own skin and see a doctor if a wart looks unusual, grows quickly, or does not go away after reasonable time.

Complications

If left untreated

• Warts may spread to other parts of your body
• Warts may spread to other people through close skin contact or shared items
• Warts on the soles of your feet can become painful if they grow large
• Rarely, a wart may become infected if you pick at it

Long-term outlook

The outlook is very good. Most warts disappear on their own within two years, and treatments can speed that up. Warts are harmless and rarely cause long-term problems. Your immune system is your best ally, and with patience and the right care, most warts clear completely.
