Cervical cancer usually develops slowly from abnormal cells on the cervix. Screening can identify these precancerous changes before they become cancer, allowing treatment at an earlier and more effective stage. This is why screening is valuable even when a woman feels completely well.
What is cervical cancer screening?
Cervical screening is not a test for every possible reproductive-health condition. It is designed to find human papillomavirus (HPV) infection or abnormal cervical cells that may need monitoring or treatment. Common screening approaches include HPV testing, visual inspection with acetic acid (VIA) and cervical cytology, sometimes called a Pap test. The method offered depends on the health system, facility and individual situation.
When should you start?
The recommended age to start, the preferred test and the time between tests can vary by country, HIV status, previous results and available services. Rather than relying on one schedule copied from another country, ask a qualified provider or recognised screening programme which guidance applies to you.
Women living with HIV generally need earlier and more frequent cervical screening because persistent high-risk HPV infection is more likely. Anyone who has previously had an abnormal screening result or treatment for cervical precancer should follow the personalised follow-up plan provided by their clinician.
Do not wait for symptoms
Screening is meant for people without symptoms. Early cervical cell changes often cause no warning signs. Waiting for pain or bleeding can miss the opportunity to identify precancerous changes.
Symptoms that need clinical assessment
These symptoms do not automatically mean cervical cancer, but they should be checked:
- Bleeding after sexual intercourse.
- Bleeding between menstrual periods.
- Bleeding after menopause.
- Unusual or persistent vaginal discharge.
- Persistent pelvic pain or pain during sex.
When symptoms are present, tell the provider clearly. You may need a clinical examination rather than routine screening alone.
Preparing for a screening visit
- Ask which test will be used and when results will be available.
- Tell the provider if you are pregnant, recently delivered, menstruating or using vaginal medicines.
- Share previous abnormal results or treatment information.
- Ask what the next step will be if the result is positive or unclear.
What if the result is positive?
A positive HPV test does not mean you have cancer. HPV is common, and many infections clear without causing serious disease. A positive result means follow-up is important. The provider may recommend another test, examination or treatment of precancerous cells, depending on the screening method and result.
HPV vaccination and screening work together
HPV vaccination can prevent infection from important cancer-causing HPV types, but vaccinated women may still need cervical screening according to local guidance. Vaccination does not treat an infection that already exists, and screening remains an important part of prevention.
Your next practical step
If you have never been screened, do not remember your last test, live with HIV, or have had an abnormal result, contact a recognised facility and ask what screening schedule is recommended for you. Early action can prevent many cervical cancer cases.
