HPV is a virus easily spread skin-to-skin during genital, anal, or oral sex (penetration is not required). HPV is known as the “common cold” of sexually transmitted infections as approximately 75% of sexually active Canadians will have at least one HPV infection in their lifetime. HPV can cause a variety of cancers, no matter your sex, gender or sexual orientation. Nearly all cervical cancers are caused by infection with HPV.
HPV infection does not usually involve any symptoms and you can pass the virus on to someone else without knowing it. HPV usually goes away without treatment. For some people, however, HPV will not clear on its own, and cervical cells infected with HPV become cancerous over time. These changes happen slowly – it usually takes 15-20 years for HPV to develop into cervical cancer.
Anyone with a cervix who has ever been sexually active (skin contact or intercourse) is at risk of transmitting HPV, but the risk increases if you:
- started having sexual activity at a young age (under 18 years);
- have a history of other sexually transmitted infections;
- have weakened immunity;
- smoke;
- do not use condoms.
In addition to cervix cancer, HPV can lead to vaginal cancer, vulvar cancer, anal cancer, and genital warts.
