One type of cancer that only women can get is cancer of the cervix, or cervical cancer. Most cervical cancer is caused by human papillomavirus (HPV). The only sure way to find out if you have cervical cancer is to get a Pap test or a Pap-HPV co-test, which includes HPV testing with the Pap test. For most women, the best practice is to get a Pap test every three years (for ages 21 to 65) or to get the Pap-HPV co-test every five years (for ages 30 to 65). If you are a woman who has not had her cervix removed by surgery (a hysterectomy), keep getting tested until you are at least 65 years old.

However, a recent study found that some women do not continue to get screened for cervical cancer as they get closer to 65 years old. Unfortunately, you can still get cervical cancer when you are older than 65 years. The only way to know it is safe to stop being tested after age 65 is if you have had several tests in a row that didn’t find cancer within the previous 10 years, including at least one in the previous five years.

  • For the Pap test alone, you should have three normal tests in a row.
  • For the Pap-HPV co-test, you should have two normal tests in a row.
  • Screening after age 65 may be appropriate for some women at high risk, including women with a history of cervical lesions or cancer, women whose mothers took a hormone called diethylstilbestrol (DES) while pregnant, or women who have a weakened immune system. Women at high risk should talk with their doctors about how often to get screened and until what age.

How the Study Worked

The researchers wanted to know how many women between 41 and 70 years old had never had a Pap test or co-test, or hadn’t had one in the five years before the survey. They looked at answers to questions about cervical cancer testing in the National Health Interview Survey. The questions were asked in 2013 and 2015. The researchers also looked at information from two federal cancer registry programs to see how the chance of getting cervical cancer changes with age among women who have not had a hysterectomy. (Cancer registries are used to keep detailed records about cases of cancer.)

What the Study Found

  • The older women get, the more likely it is that they have never been tested or haven’t been tested in the previous 5 years.
  • About one woman out of 20 between 66 and 70 years old has never been tested.
  • An older woman, until she’s in her 80s, who has not had a hysterectomy, is at least as likely to get cervical cancer as a younger woman.
  • Cervical cancer incidence rates increased with age and were higher for black women than white women.

What This Means

  • If you are a woman between 21 and 65 years old, who hasn’t had a hysterectomy and hasn’t had a cervical cancer screening test in the past 5 years, ask your doctor about getting one.
  • If you are a woman older than 65 years who has not had a hysterectomy, talk to your provider about your risk for cervical cancer and whether you still might benefit from testing.
  • Health care staff, as part of regular check-ups, could review the health records of older women patients or ask about past cervical cancer screening tests before deciding it’s safe to stop screening for cervical cancer.
  • For all women between 21 and 65 years old, with no recent history of Pap tests or co-tests, health care staff can counsel them about the importance of getting a screening test.
