Anal Warts

Anal warts are caused by HPV (human papillomavirus), which is spread through sexual contact. Transmission does not require anal intercourse—any direct contact with the anal area can spread the virus. An HPV vaccine is available and recommended to help prevent infection. HPV can also lead to anal intraepithelial neoplasia (AIN), a precancerous condition that, if left untreated, may increase the risk of anal cancer. HPV is also linked to both cervical and anal cancer.

Anal warts are often painless and may go unnoticed. Some people experience small bumps or growths around the anus, itching, minor bleeding, or mucus discharge. Diagnosis is made through a physical exam and, if needed, a brief internal exam. Patients with certain anal warts are referred to us for treatment. Treatment depends on the size and number of warts and may include topical medications, freezing or chemical treatments, or surgery. Follow-up care is important, as warts can recur.
