2022年4月26日 · HPV 16 and 18 are high-risk types known to significantly increase the risk of cervical, vaginal, and vulvar cancer in women, as well as penile cancer in men.

Certain strains of HPV (most often types 16 and 18) can cause changes in the cells of your cervix, a condition called cervical dysplasia. Left untreated, cervical dysplasia sometimes advances to cervical cancer. If you’re under 30, most HPV infections clear up on their own.

2017年5月4日 · Discovering HPV strains 16 and 18 allowed physicians to test for those cancer-causing cell populations using Pap smears, a diagnostic tool that collects cells from the woman's cervix to identify cancerous cases of HPV infection.

2025年1月31日 · HPV is a group of more than 200 related viruses, some of which are spread through vaginal, anal, or oral sex. Sexually transmitted HPV types fall into two groups: low risk and high risk. High-risk HPVs can cause several types of cancer. There are 12 high-risk HPV types: HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59.

HPV 16, HPV 18, HPV 31, HPV 33, and HPV 42 are examples of high-risk HPV types that can cause cancer. These HPV types can sometimes avoid the body's immune system, so the body can't get rid of the HPV.

2024年9月9日 · Testing HPV-positive but 16- and 18-negative means an HPV infection is present, but it does not include HPV-16 or HPV-18, two types that pose a higher risk of cancer. HPV-16 and HPV-18 are high...

HPV-16 is one of the top causes of invasive cervical cancers and accounts for 60% of all throat cancers. HPV-16 is six times more common in men than women between the ages of 18 to 69. There is also a strong association between 16 and anal cancer.

2024年4月23日 · Type 16 is the cause of approximately 50% of cervical cancers worldwide, and types 16 and 18 together account for about 66% of cervical cancers. An additional five high-risk types, 31, 33, 45, 52, and 58, are responsible for another 15% of cervical cancers and 11% of all HPV-associated cancers.

While more than 100 types of HPV exist, only about a dozen of them are associated with cervical disease. “Together, HPV 16 and HPV 18 account for 70 percent of all cervical disease,” says Trimble. Genital warts are a form of low-risk HPV, and they do not cause cancer.
