Examinations and Tests
Warts are usually diagnosed based only on their
appearance.
In rare cases, more testing is done. If the diagnosis of a skin
condition is unclear or if you are at high risk of having skin cancer, your
health professional may take a sample of the growth and examine it (a
skin biopsy). A biopsy is usually done if a skin
growth is darker than the skin surrounding it, appears as an irregular patch on
the skin, bleeds, or is large and growing rapidly.
Proper diagnosis of
plantar warts is important. Some wart treatments can
cause scarring.
