Cervical screening (Pap test): what it means
Cervical screening, also called a Pap test, Pap smear or smear test, is a quick test in which a small sample of cells is taken from the cervix to check for high-risk HPV and abnormal cell changes that could develop into cervical cancer if left untreated. It is a prevention test, not a cancer test, and is usually offered every 3 to 5 years.
What happens
You lie on your back with knees bent. A speculum is gently inserted to see the cervix, and a small soft brush collects cells around the cervical os. It takes a few minutes. It can feel uncomfortable, but shouldn't be painful: you can ask for a smaller speculum or to stop at any time.
How often
| Where | Typical schedule |
|---|---|
| UK (NHS) | HPV test every 3 to 5 years from age 25 to 64, depending on age and nation |
| US (ACOG / USPSTF) | from 21: Pap every 3 years; from 30: HPV test every 5 years or co-testing |
Follow your local program, which may change as guidance is updated. Some places now offer self-sampling kits.
Best time in your cycle
Many clinics prefer a time when you are not bleeding, often the follicular phase after your period, as heavy blood can affect the sample. Avoid lubricants or vaginal creams for two days before unless your clinic says otherwise. If you feel anxious, telling the nurse helps; you can also bring someone with you.
Don't wait for your next screening if you have bleeding between periods, after sex or after menopause, unusual discharge, or pelvic pain. See a doctor about these at any time. Screening is for people without symptoms.
If sex or exams are very painful or impossible, see vaginismus; you can still be screened with extra support.
Frequently asked questions
What does an abnormal result mean?
Usually HPV or mild cell changes, most of which clear on their own. You may be invited for a repeat test or a closer look called a colposcopy.
Do I need screening if I've had the HPV vaccine?
Yes. The vaccine prevents most but not all high-risk HPV types, so screening is still recommended.
