What is anal HPV?
Anal HPV means the virus is present in the anal area, and it usually clears on its own. Low-risk types can cause anal warts, while persistent high-risk infection can, rarely, lead to precancerous changes in the anal area. The risk is higher especially in people with a weakened immune system. Evaluation of the anal area is outside the field of obstetrics and gynecology; the relevant specialties are general surgery / proctology (and dermatology when needed), and this page is for general information only.
Anal HPV is a topic people rarely talk about but often wonder about. This page covers it plainly and without embarrassment — and clearly shows where the specialty boundary lies. Assoc. Prof. Dr. Emre Mat's field is obstetrics and gynecology and gynecologic oncology; evaluation of the anal area falls under general surgery/proctology (and dermatology when needed). The information here is for general awareness only.
What is anal HPV?
Anal HPV means HPV is present in the anal area. Like genital HPV, it is common and usually clears on its own. Low-risk types can cause warts, while persistent high-risk types can, rarely, lead to precancerous changes.
How does it spread?
It spreads mainly through skin-to-skin contact in the area and through sexual contact. The virus can be present in this area even without anal sex, through close contact in the region. The presence of the virus does not show when it was acquired.
Anal warts
Anal warts are usually caused by low-risk types (6, 11) and do not cause cancer; however, they can cause itching and discomfort and may need treatment. The treatment method is chosen by a doctor in the relevant specialty.
Do not try to cut, burn or pull off warts at home — this carries a risk of infection and wounds. General information on warts: genital warts (condylomata acuminata).
The link with anal cancer, and risk groups
Persistent high-risk anal HPV is, rarely, associated with precancerous changes in the anal area. The risk is higher especially in the following groups:
- People with a weakened immune system (e.g., people living with HIV, or after an organ transplant),
- People with a previous history of HPV-related disease in the anal area.
For these groups, the relevant specialist may recommend closer follow-up. The overall picture of cancer risk: HPV and cancer risk.
Who gets an anal Pap test?
Unlike cervical screening, anal screening (anal Pap test / high-resolution anoscopy) is not a general practice. It is usually done only in high-risk groups and at the decision of the relevant specialist. Routine anal screening is not recommended for low-risk people without symptoms.
Which specialty should you see?
Anal warts, complaints in the anal area, further evaluation.
Wart lesions on the skin surface.
If a weakened immune system (e.g., HIV) is involved.
When should you see a doctor?
- If you notice a wart, a lump or a change that does not go away in the anal area,
- If you have persistent itching, bleeding or discomfort,
- If you have a condition that weakens your immune system (for closer follow-up).
In short: anal HPV usually clears on its own. If you have complaints, the right place to go is proctology/general surgery; this page does not make a diagnosis, it points you in the right direction.
Frequently asked questions
How does anal HPV spread?
It spreads mainly through skin-to-skin contact in the area and through sexual contact. The virus can be present in this area even without anal sex, through close contact in the region.
Are anal warts dangerous?
Anal warts are usually caused by low-risk types and do not cause cancer; however, they can be uncomfortable and may need treatment. Evaluation and treatment are done by a doctor in the relevant specialty; do not try to treat them at home.
Who is at higher risk from anal HPV?
The risk is higher in people with a weakened immune system (e.g., people living with HIV, or after an organ transplant) and in people with a previous history of HPV-related disease in the anal area; closer follow-up may be recommended for these groups.
Is an anal Pap test (anal cytology) done for everyone?
No. Anal screening is not a general practice like cervical screening; it is usually done only in high-risk groups and at the decision of the relevant specialist.
Which specialty should I see for anal HPV?
Complaints in the anal area are outside the field of obstetrics and gynecology. General surgery/proctology is the right place for anal warts and complaints, and dermatology for skin lesions.
Can anal HPV be prevented with the vaccine?
The HPV vaccine protects against the main types that cause anal warts and HPV-related changes in the anal area. Discuss whether it is suitable for you with your doctor.
