Cervical cancer grows very slowly, and the HPV test picks up the risk well in advance. That's why, from 30 to 65, a normal HPV test, alone or with a Pap, is good for 5 years. With a Pap alone, or from 21 to 29, it's every 3 years. HIV, a weakened immune system or a recent abnormal result calls for screening more often.

Why does my doctor say an STD test matters more than a Pap test?

The Pap test and an STI test look for different things, so ideally you keep both up to date. The Pap test checks for the changes HPV leaves in the cells of the cervix. At your visit, ask which infections your STI test covers and when your next Pap or HPV test is due.

If my last Pap test was normal, can I really wait four years for the next one?

Yes, if it included an HPV test and you're 30 to 65, since then the interval is 5 years. With a Pap test alone, the next one is due in 3 years. No test is perfect, and a result can be normal even when a lesion is there. So abnormal bleeding, pain or new discharge gets checked right away, not at your next screening.

How often should I get a Pap test, and what does it depend on?

From 21 to 29, a Pap test every 3 years. From 30 to 65, a Pap every 3 years or an HPV test every 5, alone or with a Pap. The American Cancer Society suggests starting at 25 with HPV testing every 5 years. With HIV, a weakened immune system, or a recent abnormal result, screening may be more frequent.
