Warts are skin conditions that occur as a result of viral infections.
(Recall that the skin is also known as the "integument", or "integumentary system".)
More specifially, a wart is a benign growth on the skin caused by an infection with 'human papillomavirus'. As a few of the many types of this virus are considered causal factors in the production of tumours, it is generally recommended that new / unknown growths on the skin be checked by a qualified person without delay.
Types of warts:
- Common warts form horny papules (1-10mm in diameter) usually located on the backs of the hands. Most will clear spontaneously within two years.
- Plantar warts (or verrucae) can occur on the soles of the feet and are often tender and especially sensitive to pressure.
- Plane warts are flat, skin coloured, and therefore difficult to see. They are usually located on the face and may be present in very large numbers.
- Genital warts are frequently associated with other genital infections. Infected women have an increased risk of developing cervical cancer (see also cervical cancer news).
