Warts occur in a variety of types and locations, such as the hands, feet, and in the genital area. Half of all warts go away in one year with no treatment. Two-thirds are gone after two years. They are also seen around the nails and cuticles, especially in children who bite their nails or pick at hangnails. Warts on the sole of the feet are known as plantar warts.
Warts grow inward, instead of outward, on areas that bear weight, such as the soles of the feet.
These inward growing warts can also occur on the palms of the hands. People who sweat heavily, who walk or exercise frequently are susceptible to the development of warts. Flat warts on most of the rest of the body are smaller and smoother than the warts found on the hands or feet. They grow in clusters of 20 to 100 at a time in the bearded area on the face of men and on the legs of women. Genital warts are very contagious and occur on the genitalia, around the anus, and within the rectum.
