The American Cancer Society recommends that women follow these guidelines to help find cervical cancer early as well as finding pre-cancers:
Women should start cervical cancer screening at age 21. Women 21 to 29 should have a Pap test every three years, and beginning at 30, the preferred way to screen is with a Pap test combined with an HPV test every 5 years, continuing to age 65. Another option for testing starting at 30 is to be tested every three years with just the Pap test.
Women at high risk for cervical cancer may need to be screened more often and should consult with their healthcare provider.
Women over 65 who have had regular screenings in the previous 10 years should stop cervical cancer screenings as long as they haven’t had any serious pre-cancers found in the last 20 years.
