HPV types other than 16 and 18 can still cause health issues, but generally pose a lower cancer risk.
Understanding HPV Beyond Types 16 and 18
Human Papillomavirus (HPV) is a group of more than 200 related viruses. Among these, types 16 and 18 are notorious for causing the majority of HPV-related cancers, especially cervical cancer. But what about the other types? Is HPV not 16 18 bad? The short answer is yes—it can still be problematic, but the level of risk varies widely depending on the specific strain.
HPV types are broadly classified into low-risk and high-risk categories. Low-risk types often cause benign conditions like genital warts, while high-risk types have the potential to cause cellular changes that may lead to cancer over time. Types 16 and 18 fall into the high-risk category and are responsible for about 70% of cervical cancers worldwide. However, other high-risk types exist and contribute to the remaining cases.
High-Risk HPV Types Other Than 16 and 18
While HPV-16 and HPV-18 grab most headlines, several other high-risk strains deserve attention. These include types such as 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. They have been linked to cervical precancers and cancers but tend to be less common or less aggressive in their progression.
Studies show that these other high-risk HPV types account for roughly 20-30% of cervical cancer cases worldwide. Some of them also play roles in cancers of the anus, penis, vagina, vulva, and oropharynx. The risk they pose is real but generally lower compared to types 16 and 18.
The Risk Spectrum: How Dangerous Are Non-16/18 Types?
The degree of danger depends on several factors:
- Persistence: High-risk HPV infections that persist for years are more likely to cause cell changes.
- Immune Response: A strong immune system can often clear infections before they become problematic.
- Co-factors: Smoking, multiple sexual partners, early sexual activity, or co-infections can increase risk.
Non-16/18 high-risk HPVs typically show a slower progression towards cancerous changes compared to HPV-16 or -18. However, this doesn’t mean they’re harmless. Persistent infection with any high-risk type requires monitoring.
The Role of Low-Risk HPV Types
Low-risk HPVs like types 6 and 11 do not usually cause cancer but are responsible for about 90% of genital warts cases. These warts are benign growths on the skin or mucous membranes but can be uncomfortable or embarrassing.
Even though these low-risk types don’t lead to cancer directly, their presence indicates exposure to HPV infection in general. It’s important to remember that having one type does not protect you from others.
How Common Are Non-16/18 Infections?
HPV infections are incredibly common worldwide—most sexually active people will get some form during their lifetime. Many infections clear up on their own without causing symptoms or health problems.
Non-16/18 HPVs often make up a significant portion of detected infections during routine screening tests. For example:
| HPV Type Category | Prevalence in Screening | Cancer Risk Level |
|---|---|---|
| HPV-16 & HPV-18 | ~20% | Highest (70% cervical cancers) |
| Other High-Risk Types (31,33,etc.) | ~10-15% | Moderate (20-30% cervical cancers) |
| Low-Risk Types (6,11) | ~5-10% | Low (genital warts only) |
This table gives a snapshot of how frequently these different groups appear in screenings and their relative risks.
The Importance of Screening for All High-Risk Types
Pap smears and HPV DNA tests are vital tools in catching abnormal cell changes early—before they turn into cancer. Modern screening tests don’t just look for types 16 and 18; many also detect a panel of other high-risk HPVs.
If you test positive for any high-risk type—not just HPV-16 or -18—your healthcare provider will likely recommend closer follow-up or additional testing such as colposcopy (a detailed examination of the cervix). This is because persistent infection by any high-risk type can lead to precancerous lesions.
Treatment Options When Non-16/18 HPVs Are Detected
There’s no direct cure for the virus itself yet; treatment focuses on managing abnormal cells caused by persistent infection:
- Cryotherapy: Freezing off abnormal tissue.
- LLETZ/Loop Excision: Removing affected tissue with a wire loop.
- Surgical Procedures: For more severe precancers.
- Regular Monitoring: To track changes over time.
Most mild abnormalities caused by non-16/18 HPVs resolve on their own with monitoring alone. Only persistent or worsening lesions require intervention.
The Role of Vaccination Against Non-16/18 HPVs
Vaccines like Gardasil® protect against several high-risk HPV types beyond just 16 and 18. For example:
- Gardasil®9: Covers nine strains including HPV types: 6,11 (low risk), plus seven high risk including 31,33,45,52,&58.
- Cervarix®: Protects mainly against types 16 &18.
Widespread vaccination has dramatically reduced infections from vaccine-covered strains in vaccinated populations. This reduces overall cancer risk even from non-16/18 types included in vaccines.
Vaccination is effective before exposure to the virus—ideally given during preteen years—but can still benefit adults too.
The Impact of Vaccination on Non-16/18 Strains
By covering multiple strains beyond just the two most dangerous ones (HPV-16 & -18), vaccines reduce the prevalence of other oncogenic HPVs that contribute significantly to cancer risk.
This broad protection helps lower rates not only of cervical cancer but also other HPV-related cancers such as anal or throat cancers linked with these non-16/18 strains.
The Reality: Is HPV Not 16 18 Bad?
So let’s circle back: Is HPV not 16 18 bad? It depends on what you mean by “bad.” If “bad” means dangerous enough to cause serious health problems like cancer—the answer is yes for some non-16/18 strains but with generally lower frequency and slower progression compared to types 16 and 18.
Non-16/18 high-risk HPVs still warrant attention due to:
- Their ability to cause precancerous lesions.
- Their contribution to a significant minority of cervical cancers worldwide.
- Their presence in other anogenital and head-and-neck cancers.
Low-risk types aren’t “bad” in terms of cancer but can cause discomfort through warts or recurrent infections.
A Balanced Viewpoint on Risk Management
It’s important not to panic if you test positive for an HPV type that isn’t one of the big two (or even if it is). Most infections clear naturally within one to two years without causing anything serious.
Good sexual health practices combined with regular screening create your best defense against developing complications from any HPV infection type—whether it’s type 6 or type 58.

Frequently Asked Questions
Is HPV Not 16 18 Bad for Causing Cancer?
HPV types other than 16 and 18 can still cause cancer, but they generally pose a lower risk. Several other high-risk types contribute to about 20-30% of cervical cancer cases worldwide, so monitoring these infections is important despite their lower aggressiveness.
How Dangerous Is HPV Not 16 18 Compared to Types 16 and 18?
HPV types beyond 16 and 18 tend to progress more slowly toward cancerous changes. While they are less aggressive, persistent infections with these high-risk types still require attention, as they can cause cellular abnormalities and increase cancer risk over time.
Can Low-Risk HPV Not 16 18 Be Harmful?
Low-risk HPV types, like 6 and 11, are not typically linked to cancer but can cause genital warts. These warts are benign but may cause discomfort or embarrassment. Low-risk types do not lead to cancer like high-risk strains do.
What Factors Affect the Risk of HPV Not 16 18?
The danger from HPV types other than 16 and 18 depends on persistence of infection, immune system strength, and co-factors such as smoking or multiple sexual partners. A strong immune response often clears the virus before it causes serious problems.
Should I Be Concerned About HPV Not 16 18 Infections?
Yes, while HPV not types 16 or 18 usually pose a lower risk, some can still lead to precancerous changes or other health issues. Regular screening and medical follow-up are important for managing any high-risk HPV infection effectively.
Conclusion – Is HPV Not 16 18 Bad?
Yes—certain non-HPV-16/18 strains carry risks that shouldn’t be ignored. They contribute meaningfully to cervical and other cancers though less aggressively than the top two offenders. Vaccines covering multiple strains help reduce this burden significantly.
Regular screenings remain crucial because they catch abnormal changes early regardless of which strain causes them. If you test positive for a non-16/18 type, follow-up care ensures timely management before serious issues develop.
In short: Is HPV not 16/18 bad? It can be—but knowledge plus proactive healthcare keeps you ahead in protecting your health every step of the way.
