Cervical cancer can often be prevented by having regular screening to find any precancers so they can be treated. Preventing precancers means controlling possible risk factors, such as:
Delaying first sexual intercourse until the late teens or older
Limiting the number of sex partners
Avoiding sexual intercourse with people who have had many partners
Avoiding sexual intercourse with people who are obviously infected with genital warts or show other symptoms
In 2006, the FDA approved the first HPV vaccine, called Gardasil, for girls and women between ages 9 and 26. The vaccine helps prevent infection from the 2 HPV strains known to cause most cervical cancer and precancerous lesions called HPV-16 and HPV-18. The vaccine also prevents against 2 low-risk HPV strains that cause 90% of genital warts. In 2009, the FDA approved a second HPV vaccine, called Cervarix, for the prevention of cervical cancer in girls and women ages 10 to 25. These vaccines do not protect people who are already infected with HPV. Learn more about HPV vaccination for cervical cancer .
Screening is used to look for cancer or abnormalities that may become cancerous before you have any symptoms or signs. Scientists have developed, and continue to develop, tests that can be used to screen a person for specific types of cancer before signs or symptoms appear. The overall goals of cancer screening are to:
Reduce the number of people who die from the cancer, or completely eliminate deaths from cancer
Reduce the number of people who develop the cancer

Screening information for cervical cancer
The following tests and procedures may be used to screen for cervical cancer:
Bimanual pelvic exam
In this examination, the doctor will check a woman’s body for any unusual changes regarding her cervix, uterus, vagina, ovaries, and other nearby organs. To start, the doctor will look for any changes to the woman’s vulva outside the body and then, using an instrument called a speculum to keep the vaginal walls open, the doctor will look inside the woman’s body. Some of the nearby organs are not visible during this exam, so the doctor will then insert two fingers of one hand inside the patient’s vagina while the other hand gently presses on the lower abdomen to feel the uterus and ovaries. This exam typically takes a few minutes and is done in an examination room at the doctor’s office.
This test is done on a sample of cells removed from the woman’s cervix, the same sample used for the Pap test (see below). This sample is tested for the strains of HPV most commonly linked to cervical cancer. HPV testing may be done by itself or combined with a Pap test (see below). This test may also be done on a sample of cells from a woman’s vagina that she can collect herself.
The Pap test  has been most common test for early changes in cells that can lead to cervical cancer. This test is also called a Pap smear. A Pap test involves gathering a sample of cells from the cervix and is often done at the same time as a pelvic exam (see above). HPV testing may be done along with a Pap test.
Screening recommendations for cervical cancer (Updated 10/2016)
Different organizations have looked at the scientific evidence, risks, and benefits of cervical cancer screening. These groups have developed different screening recommendations for women in the United States who have “average risk” of cervical cancer, meaning these women do not have strong risk factors  for this disease.
ASCO recommends that all women receive at least one HPV test for cervical cancer screening for cervical cancer once in a lifetime. Though, ideally, women age 25 to 65 should receive screening with the HPV test every 5 years. Women age 65 and older may stop screening if their HPV test results have been mostly negative over the previous 15 years. Sometimes, women age 65 and older who have tested positive for HPV may continue screening until age 70.
Decisions about screening for cervical cancer are becoming increasingly individual. Sometimes, screening may differ from the recommendations discussed above as a result of a variety of factors. Such factors include the availability of testing and follow-up options in your area, personal risk factors, and your health history. It’s important to talk with your health care team or a health care professional knowledgeable in cervical cancer screening about how often you should receive regular screening and which tests are most appropriate.
Here are some questions to ask a health care professional about:
At what age should I start being screened for cervical cancer?
Should my screening include an HPV test? If so, how often?
Why are you recommending these specific tests and screening schedule for me?
At what age could I stop being regularly screened for cervical cancer?
Do any of these recommendations change if I have had cervical dysplasia or precancer?
Do any of recommendations change if I have HIV?
Do any of these recommendations change if I have had a hysterectomy?
Do any of recommendations change if I am pregnant?
Do any of recommendations change if I have had the HPV vaccine?
What happens if the screening shows positive or abnormal results?
All women should talk with their doctors about cervical cancer and decide on an appropriate screening schedule. For women at high risk for developing cervical cancer, screening is recommended at an earlier age and more often than women who have an average risk of cervical cancer.
