A WART is an intra epidermal or skin tumor caused by a variety of
viruses. The many varieties of warts that exist are named by the way
they appear or where they are located. A wart is a small, circumscribed
tumor of the outer or horny layer of the skin. There are flat and smooth
warts as well as elevated warts, warts that are firm and rise from the
surrounding skin.
Mainly caused by the Human Papilloma Virus(HPV), they
vary in size and may be accompanied by pain, especially if they occur in
the feet (plantar warts). The Human Papilloma Virus belongs to the
family of viruses that causes warts and has been implicated as a
possible cause of genital cancers and, more recently, cancers and other
abnormal growths of the eye.
