Understanding HPV: What It Is and How It Spreads

Human papillomavirus, or HPV, is one of the most common viruses that affects people worldwide. According to the Centers for Disease Control and Prevention (CDC), nearly 80 percent of people will contract at least one type of HPV during their lifetime. Despite how common it is, many people don't fully understand what HPV is or how it works in the body.

HPV is a small virus that infects the skin and mucous membranes. There are more than 200 types of HPV identified by medical researchers, but only about 14 of these are considered high-risk types that can lead to cancer. The remaining types are considered low-risk and typically cause no serious health problems. Some low-risk types cause genital warts, which are benign growths that appear on or around the genitals.

The virus spreads through skin-to-skin contact, most commonly during sexual activity. This includes vaginal, anal, and oral sex. HPV can spread even when an infected person has no visible symptoms or warts. A person can carry the virus for years without knowing they have it. Importantly, HPV does not spread through blood, saliva, sharing food, or other casual contact methods.

Most people who contract HPV never develop any symptoms or health problems. The immune system typically clears the infection within one to two years on its own. However, in some cases—particularly with high-risk HPV types—the virus persists in the body. When this happens, it may lead to precancerous changes in cells or, in some instances, cancer over many years.

Practical takeaway: Understanding that HPV is extremely common and that most infections clear on their own can reduce anxiety. If you receive an HPV diagnosis, it does not automatically mean you will develop cancer or experience serious health effects.

How HPV Is Diagnosed and Detected

HPV diagnosis typically occurs through testing performed by a healthcare provider during a routine medical exam. The methods used to detect HPV vary depending on the type of infection and the area of the body being examined. Understanding these testing methods can help you know what to expect if your doctor recommends HPV screening.

For cervical HPV, the most common screening method is the HPV test, sometimes called an HPV DNA test. During this procedure, a healthcare provider collects cells from the cervix using a small brush or spatula. This is often done during a regular Pap smear appointment. The Pap smear itself looks for abnormal cells, while the HPV test specifically identifies the presence of the virus. Many healthcare providers now perform both tests together, since HPV testing has become more accurate and widely available in recent years.

For genital warts caused by low-risk HPV types, diagnosis is usually straightforward. A healthcare provider can often identify warts through a simple visual examination. Sometimes, however, warts may not be immediately visible, and the provider might use a special magnifying instrument called a colposcope or apply a dilute acetic acid solution to make them more visible.

If cervical HPV testing shows high-risk types or if a Pap smear shows abnormal cells, a provider may recommend a colposcopy. During this procedure, a healthcare provider uses a colposcope to examine the cervix more closely and may take a tissue sample (biopsy) if abnormal areas are spotted. A biopsy involves removing a tiny piece of tissue for laboratory analysis, which can detect whether precancerous or cancerous changes have occurred.

In some cases, healthcare providers may also use HPV testing for other areas, including the throat or anus, depending on a person's sexual history and symptoms. Testing for these areas is less routine but may be recommended based on individual risk factors.

Practical takeaway: HPV testing is a standard part of many health screening programs and is not painful. Knowing the different testing methods available can help you understand what your healthcare provider recommends and why.

Treatment Options for Genital Warts

When HPV causes genital warts, several treatment options may help remove them. It's important to note that treating warts does not eliminate the HPV virus from the body—it only addresses the visible growths. The body's immune system may eventually clear the virus on its own, or warts may return after treatment.

Topical treatments are often the first approach doctors recommend for genital warts. Imiquimod is a cream that works by stimulating the immune system to fight the virus. Patients typically apply this cream to warts several times per week for several weeks or months. Podophyllin and podofilox are other topical treatments that work by damaging the cells of the wart. Sinecatechins, a product derived from green tea, is another topical option that may reduce wart size and appearance.

For warts that don't respond to topical treatments or that are particularly large or numerous, healthcare providers may use medical procedures to remove them. Cryotherapy involves applying liquid nitrogen to freeze the warts, causing them to fall off over time. This procedure may require multiple treatments. Laser therapy uses focused light to burn away wart tissue. Electrocautery uses electrical current to remove warts. Surgical removal is another option, where a healthcare provider surgically cuts or scrapes away the wart tissue.

The choice of treatment depends on factors including the number, size, and location of warts; a person's preferences; and what has worked previously. Some people opt not to treat warts at all if they are not causing discomfort or spreading. Warts may eventually disappear on their own as the body's immune system fights the infection, though this process can take months or years.

It's crucial to note that genital warts can recur even after successful treatment. Studies indicate that recurrence rates range from 10 to 50 percent, depending on the treatment method used and individual immune function. Regular follow-up appointments with a healthcare provider are important for monitoring wart status and addressing any new growths.

Practical takeaway: Multiple effective treatment options exist for genital warts, and your healthcare provider can help determine which approach is best based on your specific situation and preferences.

Managing Precancerous Changes and Cervical Dysplasia

When HPV testing or Pap smears reveal precancerous changes in cervical cells, healthcare providers classify these changes using a grading system that helps determine the level of risk and what type of follow-up is needed. These precancerous conditions are not cancer, but they may develop into cancer over time if left untreated. Understanding this distinction is important for managing concerns about an HPV diagnosis.

Cervical dysplasia is classified into three main grades: CIN1 (mild dysplasia), CIN2 (moderate dysplasia), and CIN3 (severe dysplasia). CIN stands for cervical intraepithelial neoplasia. Most cases of CIN1 resolve on their own within one to two years as the body clears the HPV infection. Healthcare providers typically monitor CIN1 with repeat HPV testing or Pap smears rather than immediately treating it. However, CIN2 and CIN3 are more likely to progress to cancer if untreated, so providers usually recommend procedures to remove the abnormal tissue.

The most common procedure for removing precancerous tissue is loop electrosurgical excision procedure (LEEP), also called loop excision or cone biopsy. During this procedure, a healthcare provider uses a thin wire loop heated with electrical current to remove the area of abnormal tissue. The procedure can be performed in an outpatient clinic setting with local anesthesia. Another option is a cold knife conization, where a healthcare provider uses a scalpel to remove a cone-shaped section of cervical tissue. Both procedures can be used for both diagnosis and treatment.

Laser conization is another treatment option that uses a laser beam to remove abnormal tissue. Some healthcare providers may recommend hysterectomy (surgical removal of the uterus) in specific cases, particularly for CIN3 or if abnormal changes persist after previous treatments. This is typically reserved for cases where the changes are extensive or recurrent.

After treatment for precancerous changes, follow-up care is essential. Healthcare providers typically recommend repeat Pap smears or HPV testing at regular intervals, often every three to six months for the first two years following treatment. This monitoring helps ensure that abnormal cells do not return and that
