A pap smear is a screening test for abnormal changes in the cervix including cervical cancer. The primary cause of cervical cancer is the Human Papillomavirus (HPV). It is a very common sexually transmitted virus. Most patients with HPV have no symptoms or warnings although it may present with warts. Males with HPV have no signs or symptoms. Thankfully the HPV vaccine can be given to young women (age 9-26). This will help to reduce the risk of cervical cancer.
