Available in Canada Only. General Information About Warts Warts are skin growths caused by viruses.
Warts can grow on any part of the body and their appearance depends primarily on their location.
They are more common where the skin has broken, for example where fingernails are bitten or hangnails picked. Foot warts are usually on the soles of the feet and are called Plantar warts . Most plantar warts do not stick above the surface like common warts because the pressure of walking flattens them and pushes them back into the skin. Flat Warts are smaller and smoother than other warts. They tend to grow in great numbers - 20 to 100 at a time.
