Cervical cancer screening helps find changes in the cervix before they become cancer. The cervix is the lower part of the uterus that connects to the vagina. Regular screening can catch problems early when they are easier to treat.
Two main tests are used for cervical cancer screening. The Pap test looks for abnormal cells on the cervix. The HPV test checks for human papillomavirus, which causes most cervical cancers. These tests can be done separately or together during a routine exam.
Types of Cervical Cancer Screening Tests
The Pap test, also called a Pap smear, collects cells from the cervix. A healthcare provider uses a small brush or spatula to gently scrape cells from the surface. These cells are sent to a lab where they are examined under a microscope for changes.
The HPV test looks for the virus that causes most cervical cancers. Research shows that HPV infection is found in almost all cervical cancers https://www.cancer.gov/types/cervical/hp/cervical-screening-pdq. The test uses the same cell sample as the Pap test, so both can often be done at the same time.
Co-testing combines both the Pap and HPV tests. This approach can find more abnormal cells than either test alone. Some healthcare providers prefer co-testing for women over 30 because HPV infections are more likely to persist in this age group.
Who Should Get Screened and When
Experts recommend that cervical cancer screening begin at age 21 for most women. Studies show that cervical cancer is very rare in women under 21, even those who are sexually active https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/cervical-cancer-screening.
Women ages 21 to 29 should get a Pap test every three years. HPV testing is not usually recommended for this age group because HPV infections often clear up on their own in younger women.
Women ages 30 to 65 have several screening options. They can get a Pap test every three years, an HPV test every five years, or co-testing every five years. The choice depends on personal preferences and risk factors.
Women over 65 may be able to stop screening if they have had regular normal results. Women who have had a hysterectomy for non-cancer reasons may also be able to stop screening, depending on the type of surgery they had.
What Happens During a Cervical Cancer Screening
The screening appointment usually takes place during a pelvic exam. The healthcare provider will ask you to undress from the waist down and lie on an exam table with your feet in stirrups. A sheet will cover your lower body for privacy.
The provider inserts a speculum into the vagina to gently open it and see the cervix clearly. The speculum may feel cold or cause slight pressure, but it should not be painful. Some women find it helpful to prepare for the screening by scheduling it for after their menstrual period.
Next, the provider uses a small brush or spatula to collect cells from the cervix. This takes only a few seconds and may cause mild cramping or spotting. The cell sample is placed in a liquid solution and sent to a lab for testing.
The entire screening process usually takes less than five minutes. Results are typically available within one to two weeks. Most results are normal, but if any changes are found, your healthcare provider will discuss next steps with you.
Understanding Screening Results
Normal results mean no abnormal cells or HPV were found. This is the most common result. Women with normal results can continue with routine screening according to their healthcare provider’s recommendations.
Abnormal Pap test results do not mean you have cancer. The results are often described using terms like ASCUS (atypical squamous cells of undetermined significance) or LSIL (low-grade squamous intraepithelial lesion). These terms describe different types of cell changes.
A positive HPV test means the virus was found in your cells. Many HPV infections clear up on their own within two years. High-risk HPV types are more likely to cause cell changes that could lead to cancer if not monitored.
Follow-up care depends on your specific results. Some women may need more frequent screening, while others may need additional tests like colposcopy, where a healthcare provider uses a special microscope to look more closely at the cervix.
Benefits and Limitations of Screening
Regular cervical cancer screening has led to a significant decrease in cervical cancer deaths. Research shows that screening programs have reduced cervical cancer rates by more than 60% in countries where they are widely used https://www.who.int/news-room/fact-sheets/detail/cervical-cancer.
Early detection makes treatment more effective and less invasive. When abnormal cells are found early, they can often be removed with simple procedures before they become cancer.
However, screening is not perfect. Sometimes abnormal cells are missed, which is called a false negative result. Other times, the test may suggest abnormal cells when they are actually normal, called a false positive result.
Some women may experience anxiety about screening or results. It is important to remember that most abnormal results do not mean cancer. Healthcare providers can explain results and recommend appropriate follow-up care based on individual situations.
Factors That Affect Screening Recommendations
Several factors can influence how often someone needs screening. Women who have had abnormal results in the past may need more frequent testing. Those with weakened immune systems due to HIV infection or organ transplant may also need different screening schedules.
Smoking increases the risk of cervical cancer, so women who smoke may benefit from more frequent screening discussions with their healthcare providers. Having multiple sexual partners or starting sexual activity at a young age may also affect screening recommendations.
Family history of cervical cancer is less important than for some other cancers because most cervical cancers are caused by HPV infection rather than inherited factors. However, women should discuss their family history with their healthcare providers.
Access to healthcare and previous screening history also matter. Women who have never been screened or who have not had screening for many years may need to start with more frequent testing initially.
Common Myths and Misunderstandings
Myth: Young women don’t need cervical cancer screening
While cervical cancer is rare in women under 21, screening should begin at age 21 regardless of sexual activity. However, some people incorrectly believe that very young women need screening as soon as they become sexually active. Studies show that starting screening before age 21 does not prevent cancer and may lead to unnecessary procedures https://www.cdc.gov/cancer/cervical/basic_info/screening.htm.
Myth: You don’t need screening if you’re not sexually active
While HPV is usually spread through sexual contact, the virus can sometimes be transmitted through other types of intimate contact. Additionally, women who were sexually active in the past may still need screening. Healthcare providers recommend following standard screening guidelines regardless of current sexual activity status.
Myth: Abnormal results always mean cancer
Most abnormal screening results do not indicate cancer. Many cell changes are minor and may return to normal on their own. Even more significant changes are usually pre-cancerous, meaning they could develop into cancer over time if not monitored or treated. True cervical cancer is found in only a small percentage of women with abnormal screening results.

- Screening should begin at age 21 and continue regularly through age 65 for most women
- The screening process is quick and usually causes only mild discomfort
- Most screening results are normal, and abnormal results rarely indicate cancer
- Regular screening has significantly reduced cervical cancer deaths in areas where it is widely available
- Individual screening schedules may vary based on age, risk factors, and previous results
