Anal HPV: What It Is, Why It Matters, and How to Treat It

By Dr. Rodney Kratz, Board-Certified Colon & Rectal Surgeon

What Is Anal HPV?

Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. When it affects the anal canal or surrounding skin, it’s called anal HPV. Many people with anal HPV have no symptoms at all, yet the virus can still cause important changes in tissue that require expert monitoring.

There are two main types:

• Low-risk HPV: causes anal warts (condyloma).
• High-risk HPV: causes invisible cellular changes (dysplasia) that can progress to anal cancer if untreated.

Who Gets Anal HPV?

Anyone can get anal HPV—regardless of sexual orientation or gender. It spreads through skin-to-skin contact, including anal intercourse, genital contact, or even without penetration.

Higher-risk groups include:

• Men who have sex with men
• People with a history of genital warts
• Individuals with weakened immune systems
• Patients with a history of cervical or vulvar HPV
• Anyone with new or multiple sexual partners

But many of my patients are otherwise healthy individuals who simply never noticed symptoms until something changed.

Common Symptoms of Anal HPV

Some patients feel nothing. Others experience:

• Small bumps or growths (soft, pink, or flesh-colored)
• Itching or irritation
• Minor bleeding
• Moistness or a feeling of “something there”
• Changes in bowel habits (rare)

Remember: high-risk HPV doesn’t make warts. It causes silent changes you cannot see. That’s why expert evaluation matters.

What Do Anal Warts Look Like?

Anal warts (condyloma) may appear as:

• Single small bumps
• Clusters resembling cauliflower
• Flat, smooth lesions that are easy to miss

They often spread beyond what is visible externally, which is why a colorectal surgeon performing anoscopy is the gold standard for diagnosis.

How I Diagnose Anal HPV

My exam is extremely quick—typically under 2 minutes—and performed in a private, comfortable setting. It may include:

• Visual inspection
• High-resolution anoscopy (HRA) when appropriate
• Biopsy for any concerning areas
• HPV testing for high-risk strains

You’ll understand your findings immediately and receive a clear plan.

Anal HPV Treatment Options

Treatment depends on what type of HPV is present and whether warts, dysplasia, or both are found.

1. Office-Based Wart Removal

• Cryotherapy
• Chemical treatments
• Electrocautery
• Infrared coagulation
• Excision for larger lesions

Most are fast, minimally painful, and require no downtime.

2. Treatment of High-Risk HPV / Dysplasia

If high-risk HPV has caused precancerous changes, I may recommend:

• Ablation during high-resolution anoscopy
• Targeted removal of abnormal tissue
• Ongoing surveillance every 3–12 months

My goal: eliminate disease early and prevent progression to anal cancer.

3. HPV Vaccination

The HPV vaccine is beneficial even for adults and reduces recurrence and future risk.

Can Anal HPV Turn Into Cancer?

High-risk HPV can lead to anal intraepithelial neoplasia (AIN), which can progress to anal cancer if untreated. Early treatment dramatically reduces the risk.

Most patients do extremely well with early detection and expert care.

How Long Does Anal HPV Last?

In many healthy adults, HPV clears within 1–2 years. However, persistent infection can occur, especially with high-risk strains. Treatment focuses on controlling the virus, removing visible disease, and preventing recurrence.

Prevention: How to Reduce Your Risk

• Get the HPV vaccine
• Use barrier protection
• Avoid smoking (it slows immune clearance)
• Treat warts or dysplasia early
• Schedule annual exams if you’re in a high-risk group

When to See a Specialist

You should schedule an evaluation if you notice:

• New anal bumps or growths
• Itching, bleeding, or discomfort
• A history of HPV and no recent follow-up
• A partner with HPV
• Concerns about anal cancer risk

Early evaluation is simple, quick, and reassuring.
