After the Nam Bo-ra cervical cancer news: is it too late for the HPV vaccine? (Does it work if you're sexually active?)

Recently, news of an actress's cervical cancer has led to a significant increase in people searching whether it's still worthwhile to get the HPV vaccine. To put it simply, even with sexual experience, you can still expect a preventive effect against uninfected HPV types, making vaccination worth considering.

In the clinic, women in their late 20s to 30s most frequently ask, "I've already had sexual experience, so is the vaccine still meaningful?" Today, let's calmly address the causes of cervical cancer and common questions surrounding HPV vaccination.

What Causes Cervical Cancer?

The most significant cause of cervical cancer is known to be HPV (Human Papillomavirus) infection. HPV is a very common virus, and women who have had sexual experience are highly likely to encounter it at least once in their lifetime.

However, infection does not immediately mean cancer. Most infections naturally clear up thanks to our body's immune system. Caution is needed when certain high-risk types of HPV persist for a long time. In such cases, changes can occur in cervical cells, progressing through dysplasia to cervical cancer.

Therefore, two pillars are important together:

• Reducing the risk of infection through HPV vaccination
• Early detection of cellular changes through regular screenings

More than the infection itself, the key is an environment where high-risk types persist for a long time. Therefore, those who prioritize both prevention and screening feel much more at ease.

Is HPV Vaccination Still Helpful After Sexual Experience?

This is the most frequently asked question. The vaccine is not a treatment for HPV that has already entered the body. However, it can help prevent infection from other types you haven't yet been exposed to.

In other words, even with sexual experience, you can still expect prevention against unexposed types and a reduction in the risk of future cervical cancer. The extent of the effect varies depending on an individual's infection history and age, so a decision tailored to your situation is necessary. We recommend discussing vaccination eligibility and timing during a vaccinations consultation.

When Should You Consider a Vaccination Consultation?

If you are in any of the following situations, it's advisable to consider a consultation:

• Women in their 20s to 30s who have not yet been vaccinated
• Those with sexual experience who wish to prevent infection from unexposed types
• If you haven't had a cervical cancer screening in a long time
• If you are concerned about the possibility of HPV infection

Rather than fostering vague anxiety after hearing the news, it's more helpful to accurately assess your own situation. If you're hesitant about where to start, feel free to clarify with a consultation.

How Can You Prepare for Cervical Cancer?

Among women's cancers, cervical cancer is one where the areas for proactive preparation are relatively clear. Commonly recommended methods include:

• HPV vaccination
• Regular check-ups through cervical cytology (Pap test)
• HPV testing
• Regular gynecological check-ups

Especially in the early stages, there are often no distinct symptoms, making regular check-ups when asymptomatic crucial. Performing both cervical cytology to check for cellular changes and HPV testing to identify virus types allows for a more thorough examination.

If You Have These Symptoms, We Recommend a Consultation

If you experience any of the following changes, it's advisable to consider testing:

• Bleeding after sexual intercourse
• Irregular bleeding outside of menstruation
• Frequent recurrent vaginitis
• History of HPV infection
• If you haven't had a cervical cancer screening for over a year

Symptoms vary from person to person, and even the same symptom can have various causes. If recurrent vaginitis is a concern, considering it from the perspective of HPV and chronic vaginitis can be helpful. Early detection often broadens the range of management options.

If You've Long Postponed Your Check-up

Many people have postponed their check-ups due to busy daily lives. However, for cervical cancer, detection during the asymptomatic stage is most meaningful. If you haven't had a check-up in a while, we recommend starting with a review for those who have postponed check-ups.
