Getting both the digene HPV Test and a Pap offers the most peace of mind for women 30 and older -- the age group that is most at risk of cervical cancer. If you do not have HPV and your Pap is normal, you can be confident you do not have abnormal cells that could develop into cervical cancer without being detected.
All women should begin cervical cancer screening at age 21. Women between the ages of 21 and 29 should have a Pap test every 3 years. They should not be tested for HPV unless it is needed after an abnormal Pap test result. Women between the ages of 30 and 65 should have both a Pap test and an HPV test every 5 years. It is also OK to have a Pap test alone every 3 years.
