Some types of HPV cause bumpy genital warts that do not cause cancer.
Other types of HPV are more serious and may cause cancer of the cervix, penis, vulva, anus and throat.
Routine Pap tests are done to screen women for cervical cancer.
The HPV vaccine can help prevent 70% of genital cancers and 90% of genital warts. It is recommended that young people get the vaccine before they become sexually active.
The vaccine does not have an effect on any type of HPV that a person may already have.
