Cervical cancer is almost entirely caused by HPV — and between the HPV vaccine and Pap/HPV screening, it's one of the few cancers we can nearly eliminate. The tools exist; the work is reaching everyone with them.
Virtually all cervical cancer is caused by persistent infection with high-risk HPV. That's a remarkable fact — it means a vaccine can prevent the cause, and screening can catch pre-cancerous changes years before cancer develops.
The WHO has a global elimination strategy built on vaccination, screening, and treatment. Where these reach women, cervical cancer has fallen by ~30% in recent decades. The remaining deaths are largely a problem of access, not of medicine.
📊 Data sourcesACS Cancer Facts & FiguresCDC CancerCervical cancer develops in the cells of the cervix, the lower part of the uterus. Almost all cases trace to persistent infection with high-risk types of human papillomavirus (HPV). HPV is common; most infections clear on their own, but persistent infection can slowly drive normal cells through pre-cancer to cancer over years.
That slow progression is the opening: screening catches pre-cancer before it becomes cancer, and the HPV vaccine prevents the infections that start the process. Together they make cervical cancer one of the most preventable cancers.
90%+ of cases — a vaccine-preventable virus.
The HPV vaccine blocks the types behind most cases.
Pap/HPV tests find changes years before cancer.
A clear global path to elimination exists.
A risk factor raises the odds — it doesn't guarantee the disease. Many people with risk factors never develop cervical cancer, and some with none do. The point is to know your risk so you can act on what's modifiable.
High-risk HPV infection is the central cause.
Unvaccinated people miss the strongest protection.
Most cases occur in women never or rarely screened.
Doubles risk in women with HPV.
HIV or immunosuppression raises risk.
Associated with modestly higher risk.
HPV vaccination is recommended at ages 11–12 (can start at 9) and through 26 — and it's most effective before any exposure. Screening begins at 21: Pap every 3 years, or from 25–30 onward, primary HPV testing every 5 years is preferred.
Both tools matter. The vaccine prevents the infections; screening catches anything the vaccine missed. Together they're why cervical cancer keeps falling.
📊 Data sourcesUSPSTF Screening RecommendationsCDC CancerScreening finds pre-cancerous changes early, when a simple office procedure can stop cancer before it starts. Combined with the HPV vaccine, it's the closest thing we have to a cancer off-switch.
Cervical cancer is the rare cancer with a vaccine and a screening test that, used together, can prevent the overwhelming majority of cases.
The single most powerful prevention tool — ideally before exposure.
Pap/HPV testing catches pre-cancer early.
Smoking doubles risk in women with HPV.
Especially important with HIV or immunosuppression.
Removing abnormal cells stops cancer before it starts.
Access and awareness are the remaining gaps.

The HPV vaccine plus regular screening can prevent almost every case of cervical cancer. Make sure the young people in your life are vaccinated — and keep your own screening on schedule.
