What are the 13 high-risk HPV types?
High-risk HPV types include types 16, 18, 31, 33, 34, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, and 70. Included in the high-risk group are some HPV types that are less frequently found in cancers but are often found in squamous intraepithelial lesions (SILs) (Table 1).
What are the 14 high-risk HPV types?
Currently approved tests detect 14 high-risk types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) and report results for detection of any of these types. Some tests also provide separate results for HPV 16 or 18.
How does HPV affect the body?
HPV can cause cervical and other cancers including cancer of the vulva, vagina, penis, or anus. It can also cause cancer in the back of the throat, including the base of the tongue and tonsils (called oropharyngeal cancer). Cancer often takes years, even decades, to develop after a person gets HPV.
What is HPV other high risk?
Other types of HPV are called “high-risk” because they can cause cancer in both men and women. Doctors worry more about the cell changes and pre-cancers linked to these types, because they’re more likely to grow into cancers over time. Common high-risk HPV types include HPV 16 and 18. Infection with HPV is very common.
How many cervical cancers are caused by HPV?
Number of HPV-Attributable Cancer Cases per Year
| Cancer site | Average number of cancers per year in sites where HPV is often found (HPV-associated cancers) | Percentage probably caused by any HPV typea |
|---|---|---|
| Cervix | 12,143 | 91\% |
| Vagina | 867 | 75\% |
| Vulva | 4,114 | 69\% |
| Penis | 1,348 | 63\% |
What types of HPV are there?
High-risk HPV strains include HPV 16 and 18, which cause about 70\% of cervical cancers. Other high-risk human papillomaviruses include 31, 33, 45, 52, 58, and a few others. Low-risk HPV strains, such as HPV 6 and 11, cause about 90\% of genital warts, which rarely develop into cancer. These growths can look like bumps.
What are the types of HPV?
What are HPV types 6 and 11?
HPV 6 and HPV 11 are low-risk types of HPV. They are linked to approximately 90 percent of genital warts. HPV 11 can also cause changes to the cervix. Genital warts look like cauliflower-shaped bumps on your genitalia.
What does HPV 16 and 18 negative mean?
A positive result indicates the presence of human papillomavirus (HPV) DNA due to 1 or more of the following genotypes: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. A negative result indicates the absence of HPV DNA of the targeted genotypes.
What cancers does HPV cause in females?
Almost all cervical cancer is caused by HPV. Some cancers of the vulva, vagina, penis, anus, and oropharynx (back of the throat, including the base of the tongue and tonsils) are also caused by HPV. Almost all cervical cancer is caused by HPV.
