Almost all cervical cancers are caused by human papillomavirus (HPV), a common virus that can be passed from one person to another during sex. There are many types of HPV. Some HPV types can cause changes on a woman’s cervix that can lead to cervical cancer over time, while other types can cause genital or skin warts.
HPV is so common that most people get it at some time in their lives. HPV usually causes no symptoms so you can’t tell that you have it. For most women, HPV will go away on its own; however, if it does not, there is a chance that over time it may cause cervical cancer.
Other things can increase your risk of cervical cancer:
- Having HIV (the virus that causes AIDS) or another condition that makes it hard for your body to fight off health problems.
- Using birth control pills for a long time (five or more years).
- Having given birth to three or more children.
- Having several sexual partners.
