Final answer:
Plantar warts are caused by HPV and have various treatment options including topical medications and procedures like cryotherapy, electrosurgery, and laser therapy.
Step-by-step explanation:
Plantar warts, also known as foot warts, are caused by the human papillomavirus (HPV) and usually develop on the sole of the foot. The initial treatment for plantar warts includes several options. Topical medications like imiquimod, podofilox, or sinecatechins can be applied directly to the wart. Cryotherapy, which involves freezing the wart using liquid nitrogen, is another common treatment option. Additionally, electrosurgery, laser therapy, or chemical peels may be used for wart removal. It's important to consult a healthcare professional for the appropriate treatment based on the individual's condition.
