Cervical Cancer Screening
Routine cervical cancer screening is essential for early detection, as it identifies abnormal cells or high-risk HPV infections before they develop into cancer.
What is cervical cancer screening?
Cervical cancer screening tests look for cancer before you have symptoms. Because cervical cancer develops slowly, screening can find "precancers"—abnormal cells that can be treated and removed before they become cancer.
What tests screen for cervical cancer?
Screening is usually performed during a pelvic exam using a swab to collect cervical cells:
- Pap test (or Pap smear): Checks for abnormal cells.
- HPV test: Checks for high-risk HPV infections that can cause cancer.
- HPV/Pap cotest: Checks for both high-risk HPV and cervical cell changes.
What are the possible benefits and harms of cervical cancer screening?
While screening saves lives, it has potential harms, primarily related to inaccurate results:
- False-positive result: Results appear abnormal when there are no cancerous cells, which may lead to unnecessary worry and follow-up tests.
- False-negative result: Results appear normal when precancer or cancer is present, which may lead to delayed treatment.
Should I be screened for cervical cancer?
Talk to your provider about your specific schedule based on your age and health history. General recommendations include:
- First Pap smear at age 21.
- Begin screening with an HPV test at age 25.
You may need more frequent screening if you have a history of abnormal results, a diagnosis of cervical cancer, a weakened immune system, or exposure to DES before birth. If you are over 65 and have had regular normal results, you may no longer need screening, unless you have HIV. If you have had a total hysterectomy for non-cancerous reasons, you generally do not need screening.
