Warts are small, usually painless growths on the skin. Most of the time, they are harmless. They are caused by a virus called human papillomavirus (HPV). There are more than 150 types of HPV viruses. Some types of warts are spread through sex.
All warts can spread from one part of your body to another. Warts can spread from person to person by contact, especially sexual contact.
Most warts are raised and have a rough surface. They may be round or oval.
Different types of warts include:
Your health care provider will look at your skin to diagnose warts.
You may have a skin biopsy to confirm the wart is not another type of growth, such as skin cancer.
Your provider can treat a wart if you do not like how it looks or if it is painful.
DO NOT attempt to remove a wart yourself by burning, cutting, tearing, picking, or by any other method.
Over-the-counter medicines are available to remove warts. Ask your provider which treatment is right for you.
DO NOT use over-the-counter wart medicines on your face or genitals. Warts in these areas need to be treated by a provider.
To use wart-removal medicine:
Special foot cushions can help ease the pain from plantar warts. You can buy these at drugstores without a prescription. Use socks. Wear shoes with plenty of room. Avoid high heels.
Your provider may need to trim away thick skin or calluses that form over warts on your foot or around nails.
Your provider may recommend the following treatments if your warts do not go away:
Genital warts are treated in a different way than most other warts.
Most often, warts are harmless growths that go away on their own within 2 years. Periungual or plantar warts are harder to cure than warts in other places. Warts can come back after treatment, even if they appear to go away. Minor scars can form after warts are removed.
Infection with certain types of HPV can increase cancer risk, most commonly cervical cancer in women. This is most common with genital warts. To decrease the risk for cervical cancer in women, a vaccine is available. Your provider can discuss this with you.
