How are HPV and cervical cancer related?
Human papillomavirus (HPV) is found in about 99% of cervical cancers. There are more than 100 different types of HPV, the majority of which are considered low risk and do not cause cervical cancer. High-risk HPV types may cause cervical cell abnormalities or cancer. More than 70% of cervical cancer cases can be attributed to two types of the virus, HPV-16 and HPV-18, often referred to as high-risk HPV types.
