Certain diseases caused by HPV
HPV can infect both males and females. There are 4 types of HPV that parents should know about, because they cause the majority of HPVrelated diseases.
- HPV Types 16 and 18 cause about 75% of all cervical cancer cases in females.
- HPV Types 16 and 18 can lead to about 70% of vaginal and up to 50% of vulvar cancer cases.
- HPV Types 6 and 11 cause about 90% of all genital warts cases in both males and females.
The best time to help protect your son or daughter from the potential consequences of certain HPVrelated diseases is before they are exposed to the virus.
- Cervical Cancer
Each day, another 33 women are diagnosed with cervical cancer in the United States (about 12,000 women per year). Unlike some other cancers, cervical cancer is not considered to be passed down through family genes. It is caused by certain types of HPV. When a female is infected with these types of HPV, and the virus doesn't go away on its own, abnormal cells can develop in the lining of the cervix (the lower part of the uterus that connects to the vagina). If these abnormal cells are not found early through routine cervical cancer screening and treated, precancers and then cervical cancer can develop. That's why it's important to get regular cervical cancer screenings.
DID YOU KNOW? Two types of HPV cause about 75% of all cervical
cancer cases in females.
Many females with cervical cancer were probably exposed to cancercausing HPV types in their teens and 20s. In fact, women in their teens and 20s may be more vulnerable to certain infections than adult women. That's why it's important for parents to learn how to help protect their children before they're exposed to HPV.
For most, HPV clears on its own. But, for others who don't clear certain types, HPV could cause significant consequences: cervical, vaginal, and vulvar cancers in females. Other types could cause genital warts in both males and females. And there's no way to predict who will or won't clear the virus.
- Genital Warts
Genital warts are another disease also caused by certain types of HPV. They are usually fleshcolored growths that may be raised or flat, single or multiple, small or large. But even after seeing pictures, you may not be able to recognize genital warts because they don't always look the same.
Genital warts can affect both males and females and they can be easily spread. In fact, approximately 3 out of 4 people will get them after having any kind of genital contact with someone infected. It is estimated that every minute in the United States there is a new case of genital warts.
Although genital warts can be treated, treatment doesn't cure the HPV infection that caused them. Treatment for genital warts can also be painful (for example, it may involve cutting or freezing the warts) and, even after treatment, genital warts can come back. In fact approximately 25% of all cases return within 3 months. Like other diseases, it's best to find out what you can do to help protect your son or daughter before exposure.

- Other HPVrelated Cancers
In addition to cervical cancer, HPV Types 16 and 18 cause approximately 70% of all vaginal cancer cases and up to 50% of vulvar cancer cases.
In the United States, there are about 4,490 cases of vulvar cancer per year as well as approximately 2,680 cases of vaginal cancer.*
*Not all vulvar and vaginal cases are caused by HPV.
