A wart is a small growth in the skin caused by a viral infection.

It is possible that a variety of other more serious lesions, can be mistakenly identified as warts. Because of those identification problems, it is wise to consult a podiatrist about any suspicious growth or eruption on the skin of the feet. If warts are left untreated, they can grow and spread into clusters of several warts. Most plantar warts aren’t a serious health concern, but they may be bothersome or painful, and they can be resistant to treatment. Plantar warts are very difficult to treat because we walk on them making them penetrate deeper in the skin.


  • Viruses cause warts, which typically invade the skin through small cuts and abrasions.
  • Warts are commonly contracted in communal places such as swimming pools, showers and changing areas where people are more inclined to walk barefoot.
  • Excessive moisture or excessive dryness of the skin can lead to small cracks in the skin which provides an easy entry for the virus


  • No wart treatment works all the time. In general, your podiatrist will recommend the least painful — and least destructive — methods first, especially for children.
  • There are different types of chemical treatments which are very unique to different patient’s situations.
  • Patients can try acids at home, but they are not very effective.
  • The podiatrist can use strong acids or inject Bleomycin in the wart. This last method often works in 1 to 3 treatments.
  • If the wart persists, we can do surgery, but this method also has a 10% recurrence rate.
