HPV is the most common cause of cervical cancer. Exposure to HPV can happen, even if a person has only had sex once or with only one person. Knowing the factors that can affect your risk of contracting HPV can help you identify the steps you can take to reduce your risk of developing cervical cancer.

HPV vaccines offer the greatest protection when administered prior to HPV exposure (i.e., before the onset of sexual activity). Nevertheless, those who are sexually active may still benefit from the vaccine, as they may not have been exposed to the HPV subtypes covered by the vaccine. Even in a monogamous relationship, the risk of HPV is present because an HPV infection can be asymptomatic and remain undetected for many years.
