Do all women need pap tests annually?

Can do every 3 years. At least once a yaer for every year starting at age 20 or when you start sexual activity is the standard recommendation. It you get two consecutive negative annual pap smears, then you can repeat the test every three years.
No. Start with onset of sex then depending on results of pap every 1-3 yrs until 70. Start over if you have a new consort, or if he does.
