What are warts?
Warts are raised bumps on your
skin caused by the human papillomavirus (HPV). Warts have plagued humans for
thousands of years — they have been discovered on 3,000-year-old mummies and
were mentioned by Shakespeare. Although warts are generally not dangerous, they
are ugly, potentially embarrassing, contagious, and they can be painful.
Important information about genital warts
more than 100 types of HPV, the virus that causes warts. Almost all types of
HPV cause relatively harmless warts that appear on your hands or feet. However,
there are a few strains of HPV that cause warts on, in, and around your
genitals. In women, these warts — called “genital warts” — can eventually lead
to cervical cancer, a potentially fatal disease. If you think you have genital warts or think
you have been exposed to them, you should see a doctor right away.

wart if you notice what appears to be a small hole in the bottom of your foot
that is surrounded by hardened skin. Plantar warts can make walking

noticeable. Flat warts have a flat top, as if they have been scraped. They can
be pink, brownish, or slightly yellow.

chin. They are small and shaped like a tiny flap or tag of skin. Filiform warts

want to try treating them at home. Many warts respond well to treatments
available at the drugstore.
- You can spread warts to other
parts of your body, and they are contagious to others. If a treatment requires
that you rub the wart with a fingernail file or a pumice stone, do not use that
utensil on any other part of your body, and do not allow anyone else to use it.

feet if you have diabetes. See your doctor. Diabetes can cause loss of
sensation in your feet, so you can easily injure yourself without realizing it.
