What Causes Anal Warts?

Anal warts are a contagious skin condition, often caused by human papillomavirus (HPV) infection—commonly resulting from unprotected sexual activity or sharing personal items (e.g., towels) with an infected individual. Treatment should be guided by a physician and may include topical medications such as imiquimod cream. In some cases, cryotherapy with liquid nitrogen or laser therapy may be employed for symptom relief. For severe cases, surgical removal may be necessary.
