Quick answer. Cervical cancer develops in the cervix and is strongly linked to persistent infection with the human papillomavirus (HPV). It is one of the most preventable cancers through HPV vaccination and regular screening, and any abnormal vaginal bleeding should be checked by a doctor.

Cervical cancer is a cancer of the cervix, the lower part of the womb that opens into the vagina. It is one of the few cancers we can both screen for and largely prevent, because it is strongly linked to persistent infection with the human papillomavirus (HPV). Through the HPV vaccine and regular screening, many cases can be prevented or caught very early, which is why programmes such as Screen for Life are so important for women in Singapore.
This guide explains what cervical cancer is, its symptoms, how HPV vaccination and Pap or HPV screening help prevent it, how it is diagnosed and an overview of treatment. The most important takeaway is reassuring and practical – regular screening and vaccination dramatically reduce the risk.

What is cervical cancer?
Cervical cancer is a cancer that begins in the cells of the cervix. In most cases it develops slowly, over years, from earlier cell changes (often called pre-cancer) that can be detected and treated before they ever become cancer. This slow path is exactly what makes screening so effective – it can catch problems at a stage when they are highly treatable.
Almost all cervical cancers are linked to long-lasting infection with high-risk types of HPV, a common virus that usually clears on its own. Because HPV can be vaccinated against and early changes can be screened for and treated, cervical cancer is considered one of the most preventable cancers, and Singapore supports prevention through the Screen for Life programme.
Symptoms & signs
Early cervical cancer and pre-cancerous changes often cause no symptoms at all, which is why screening matters. When symptoms do occur, they may include:
- Abnormal vaginal bleeding – between periods, after sex, or after menopause
- Bleeding after intercourse (post-coital bleeding)
- Unusual vaginal discharge
- Pain during sex
- Pelvic pain in more advanced cases
These symptoms are far more often caused by conditions other than cancer, but any abnormal vaginal bleeding should always be checked by a doctor.
Causes & risk factors
The main cause is persistent infection with high-risk types of HPV. Factors that can raise the risk include:
- Not being vaccinated against HPV
- Not attending regular cervical screening
- Smoking
- A weakened immune system
- Long-term use of some factors discussed with your doctor
Because HPV is so central, vaccination and screening together address the risk far more than any single lifestyle change.
How it's diagnosed
Cervical cancer and pre-cancer are usually found through screening and confirmed with further tests:
- Cervical screening – an HPV test and/or Pap smear to check for high-risk HPV and abnormal cells
- Colposcopy – a closer look at the cervix using a magnifying instrument if screening is abnormal
- Biopsy – a small tissue sample to confirm the diagnosis
- Imaging scans to assess the extent (stage) if cancer is confirmed
Screening through programmes such as Screen for Life is designed to detect changes early, often before any cancer develops.
Treatment options
Treatment depends on whether pre-cancerous changes or cancer are found, and on the stage. Pre-cancerous changes can often be treated with a minor procedure to remove the affected cells, preventing cancer from developing. For confirmed cancer, a specialist team plans treatment, which may include:
- Surgery
- Radiotherapy
- Chemotherapy
- A combination of these, depending on the stage
When detected early, cervical cancer is often very treatable. Prevention through HPV vaccination and regular screening remains the most powerful tool, because it can stop cancer from developing in the first place.
When to see a doctor & which specialist
See a doctor about any abnormal vaginal bleeding, bleeding after sex, bleeding after menopause, or unusual discharge. Abnormal vaginal bleeding should always be assessed by a doctor – while it is usually not cancer, it needs to be checked. If you ever experience sudden, heavy, uncontrolled bleeding or become severely unwell, treat it as an emergency and call 995.
Cervical screening and early concerns are handled by a gynaecologist, and confirmed cancer is managed by cancer specialists. You can find one through the directories of best gynaecologists in Singapore or best oncologists in Singapore. For prevention, ask your doctor about HPV vaccination and joining the Screen for Life screening programme.
Screening and vaccination in Singapore
Singapore makes cervical cancer prevention accessible through national programmes. Under the school-based HPV vaccination programme, female students in Secondary 1 and 2 are offered fully subsidised HPV vaccination, helping protect them before exposure to the virus. Eligible women can also discuss HPV vaccination with their doctor.
For screening, the Screen for Life programme offers subsidised cervical cancer screening to eligible Singaporeans and permanent residents. Women aged 30 and above are generally offered HPV testing, which can be done less frequently than the older Pap smear when results are normal. Eligible individuals receive an invitation from the Health Promotion Board, and screening is available at participating CHAS clinics and polyclinics. You can check your eligibility through HealthHub. Vaccination protects against future infection, while screening detects existing changes early, so the two work best together.
Common questions
If I have had the HPV vaccine, do I still need screening?
Yes. The vaccine protects against the most important high-risk HPV types but not every type, so regular screening is still recommended.
Is the screening test painful?
Most women find it briefly uncomfortable rather than painful. It takes only a few minutes and can be done in a clinic setting.
How often should I be screened?
This depends on your age and test type; women aged 30 and above on HPV testing are usually screened less often when results are normal. Follow the advice in your invitation letter or ask your doctor.
