子宮頸癌
HPV vaccines can prevent the most common types of infection. To be most effective, inoculation should occur "before" the onset of sexual activity, and are therefore recommended between the ages of 9–13 years. Cervical cancer screening, such as the Papanicolaou test ("pap smear"), or examination of the cervix after applying acetic acid, can detect both early cancer and abnormal cells that may develop into cancer. Screening allows for early treatment which results in better outcomes. Screening has reduced both the number of cases and the number of deaths from cervical cancer. Genital warts can be removed by freezing.
