You and your doctor can decide when it's time for you to begin Pap testing and how often you should have the test. In general, doctors recommend beginning Pap testing at age 21.
So the old recommendation of when to begin Pap smear testing has changed. This testing should start either at age 21 or three years after the start of sexual activity. (âPrematureâ Pap smears can pick up minimal changes that wonât result in cancer, but will cause concern and lead to extensive, unnecessary testing.). So, for a young teenager who is not sexually active, her first visit to a gynecologist need not include a Pap smear. But other important health issues should be addressed at this critical juncture between adolescence and adulthood.
