Warts are contagious, non-cancerous skin growths caused by a viral infection in the top layers of skin. Most are skin-colored and feel rough to the touch. Removal methods vary from acidic gels, freezing and laser treatment. There are four main kinds of warts.
- Common Warts: These warts usually grow on the fingers, around the nails and on the back of the hands. Biting fingernails and picking hangnails make skin even more susceptible to warts.
- Plantar Warts: Most commonly located on the soles of the feet, plantar warts are flat and have a reputation of being painful and feeling like a stone in the shoe.
- Flat Warts: Smaller and smoother than other warts, flat warts tend to grow in groups of 20 to 100 at any one time. They most commonly appear on the face, in a beard area in men and on the legs in women.
- Genital Warts: These warts are usually sexually transmitted and can be spread from close physical contact and repeated exposure. They are flesh-colored, rough or smooth and both large or small. Genital warts most commonly appear on the genitals, inside the vagina, on the cervix or around the anus and may evolve into skin cancer.
