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.
Talk to your doctor about how often to have this test. A high-risk type of the human papillomavirus (HPV) is the cause of most cases of cervical cancer. In women older than 30, an HPV test may be done at the same time as a Pap test.If you are age 26 or younger, you can get the HPV shot to prevent infection with the types of HPV that are most likely to cause cervical cancer. Try to schedule the test when you are not having your period, since blood can interfere with the results of the test. 2  If your bleeding is light, you may still be able to have a Pap test. 3  Do not use douches, tampons, vaginal medicines, sprays, or powders for at least 24 hours before having a Pap test.
