Genital Warts: Symptoms, Diagnosis, Treatment and Follow-Up
Genital warts are benign skin or mucosal growths that may appear on the genital area, around the anus, or rarely in the mouth and throat. They are caused by certain types of Human Papillomavirus, commonly known as HPV. Most genital warts are associated with low-risk HPV types, especially HPV 6 and HPV 11. “Low-risk” means that these types are not strongly linked to cancer, but they are still important because they can be contagious, recurrent and emotionally distressing for patients.
What causes genital warts?
Genital warts develop after infection with HPV. HPV is one of the most common sexually transmitted infections worldwide. Transmission does not require penetrative intercourse. It may occur through vaginal, anal or oral sex, as well as direct genital skin-to-skin contact. Condoms reduce the risk of transmission, but they do not provide complete protection because HPV may affect areas not covered by a condom.
“If I have genital warts, does that mean I was infected recently?”
Not necessarily. HPV can remain silent for weeks, months or sometimes longer before visible warts appear. Therefore, the appearance of genital warts does not always indicate recent transmission. This point is important because many patients experience unnecessary guilt, anxiety or relationship concerns after diagnosis.
What are the symptoms of genital warts?
Genital warts do not look the same in every patient. They may appear as skin-colored, pink, white or brownish bumps. They may be single or multiple, flat or raised, small or large, and sometimes they form clusters with a cauliflower-like appearance.
In women, they may occur on the vulva, vaginal opening, inside the vagina, on the cervix or around the anus. In men, they may appear on the penis, scrotum, groin or around the anus. Anal warts can occur even in people who have not had anal intercourse.
Some patients have no symptoms other than visible lesions. Others may experience itching, burning, tenderness, discomfort during sex, bleeding or a feeling of irritation.
“Is every bump in the genital area a genital wart?”
No. Not every genital bump is a wart. Conditions such as molluscum contagiosum, herpes, syphilis lesions, skin tags, vestibular papillomatosis, pearly penile papules and other benign skin changes may look similar. For this reason, self-diagnosis and the use of over-the-counter caustic or acidic products on the genital area are not recommended.
How are genital warts diagnosed?
In most cases, genital warts are diagnosed by visual examination performed by an experienced clinician. The location, appearance, number and size of the lesions, along with the patient’s medical and sexual history, are assessed.
HPV testing is not routinely used to diagnose genital warts because the result does not confirm the presence of warts and does not guide treatment choice. HPV testing and cervical smear testing used in cervical screening serve a different purpose: they assess the risk of cervical precancer and cancer rather than diagnose visible genital warts.
A biopsy is not needed for every patient. It may be recommended if the lesion is darkly pigmented, hardened, irregular, bleeding, ulcerated, fixed to underlying tissue, rapidly growing, not responding to treatment, or if the patient is immunocompromised.
“Do genital warts mean cancer?”
Usually, no. Genital warts are mostly related to low-risk HPV types and are generally not a sign of cancer. However, a person may carry low-risk and high-risk HPV types at the same time. Therefore, people with a cervix should continue age-appropriate cervical cancer screening according to national guidelines.
Is treatment always necessary?
Not always. Some genital warts may disappear spontaneously within months, some may remain unchanged, and others may increase in size or number. The decision to treat depends on the number, size and location of the warts, symptoms, pregnancy status, immune status and patient preference.
The main goals of treatment are to remove visible warts, reduce symptoms such as itching, burning or bleeding, improve cosmetic concerns and support quality of life. Current treatments may remove visible lesions, but they do not necessarily eradicate HPV from the skin or mucosa. Recurrence is therefore possible.
What are the treatment options?
Treatment options can be divided into patient-applied treatments and clinician-applied procedures.
1. Patient-applied treatments
Some creams or solutions may be used at home in selected patients. These medications should only be used under medical guidance. The genital area is sensitive, and incorrect use may cause burns, ulcers, pain or scarring.
This group may include immune-modulating creams or solutions that target wart tissue. The duration of treatment varies according to the medication and may take several weeks. Redness, burning, irritation, tenderness or superficial sores may occur during treatment. If these effects are severe, the patient should contact their clinician.
2. Clinician-applied treatments
Cryotherapy
Cryotherapy involves freezing the wart tissue, usually with liquid nitrogen. It is commonly used for small to medium-sized warts. Burning, pain, blistering or crusting may occur after the procedure. More than one session is often required.
Electrocautery
Electrocautery removes wart tissue using electrical energy. It may be preferred for raised, multiple or more prominent lesions. Local anesthesia may be required. Mild pain, crusting and a healing period can be expected afterward.
Surgical excision
Large, pedunculated, extensive or treatment-resistant warts may be surgically removed. Excision may also be preferred when a suspicious lesion needs pathological examination.
Laser treatment
Laser therapy may be used for extensive, recurrent or difficult-to-reach lesions. It is not necessarily the first choice for every patient and depends on availability, cost and clinical expertise.
Chemical applications
Some acidic agents can be applied directly to warts by a clinician. These treatments must be carefully controlled to protect surrounding healthy tissue.
“Which treatment is the best?”
There is no single best treatment for everyone. The choice depends on the location, number and size of the warts, pregnancy status, immune status, previous treatments, tolerance of side effects and clinician experience. Some patients may require combined or sequential treatment approaches.
Genital warts during pregnancy
During pregnancy, genital warts may grow or multiply because of hormonal and immune changes. Not all treatments are safe during pregnancy, so pregnant patients should be assessed by a clinician. In most cases, the mode of delivery is not changed solely because genital warts are present. However, special evaluation is needed if the warts are large enough to obstruct the birth canal or create a significant bleeding risk.
Partner assessment and sexual activity
Patients diagnosed with genital warts should inform their sexual partners. A partner may carry HPV even without visible lesions. Condom use reduces the risk of transmission but does not eliminate it completely. During active treatment, especially if there is irritation, open skin, bleeding or ulcers, avoiding sexual contact may be advisable.
Routine HPV testing for partners is not always necessary. However, medical evaluation is recommended if the partner has visible lesions, symptoms or a risk of other sexually transmitted infections.
Follow-up after treatment
Follow-up is important to assess whether the lesions have resolved, whether side effects have developed and whether recurrence has occurred. Warts may recur weeks or months after treatment. This does not always mean that treatment has failed; HPV may persist in the skin or mucosa for some time.
The follow-up interval varies from patient to patient, but reassessment is often performed a few weeks after treatment. Patients should return earlier if new lesions appear, existing lesions grow, bleeding or ulceration develops, or there is no improvement despite treatment.
People with a cervix should continue cervical cancer screening according to age and national screening recommendations. The presence of genital warts alone does not necessarily change the timing of Pap smear or HPV testing, but if screening is due or has never been performed, it should be addressed.
Can the HPV vaccine protect against genital warts?
HPV vaccines provide strong protection against the HPV types included in the vaccine. Some vaccines protect against HPV 6 and 11, the types most commonly associated with genital warts. The vaccine does not treat existing warts, but it may protect against HPV types the person has not yet acquired. Therefore, vaccination may still be considered in eligible individuals even if they have had genital warts before.
When should you see a doctor?
You should seek medical evaluation if you notice new bumps, itching, bleeding, pain, discomfort during sex or lesions around the anus or genital area. You should seek prompt care if the lesion grows rapidly, appears dark or irregular, bleeds, becomes ulcerated, if you are immunocompromised, or if you are pregnant.
Conclusion
Genital warts are common, treatable and usually benign manifestations of HPV infection. Proper diagnosis, individualized treatment, awareness of recurrence, partner communication, HPV vaccination assessment and appropriate follow-up help patients manage the condition safely and confidently. The best approach is shared decision-making between the patient and clinician.
