Why cervical cancer is a preventable tragedy despite being a global health crisis

In short: Cervical cancer is almost entirely linked to human papillomavirus (HPV), yet it remains the fourth-most common cancer in women worldwide. While vaccines and screening programs have dramatically reduced rates in high-income nations, nearly 90% of deaths occur in low- and middle-income countries where access to these life-saving tools is limited.

Cervical cancer develops from the abnormal growth of cells in the cervix, the lower part of the uterus. Nearly 99% of cases are linked to HPV, a virus with over 200 known types. While most people clear HPV infections naturally, high-risk strains—particularly types 16 and 18—can integrate their DNA into the host genome. This process triggers the production of viral proteins E6 and E7, which degrade tumor-suppressing proteins p53 and pRb. This disruption leads to uncontrolled cell growth and the development of tumors.

The disease typically progresses over 10 to 20 years, often remaining asymptomatic in its early stages. Because of this long lead time, regular screening is vital. Methods like the Pap test and HPV testing allow for the detection of precancerous changes, known as cervical intraepithelial neoplasia (CIN). If identified early, these lesions can be treated before they become invasive. Despite these tools, 2022 saw over 660,000 new cases and 350,000 deaths globally, highlighting a stark divide in healthcare access.

Prevention strategies are highly effective but unevenly distributed. HPV vaccines can prevent up to 90% of cervical cancers, yet the WHO goal of vaccinating 90% of girls by 2030 remains a challenge, with global coverage at 13% in 2021. Beyond vaccination, factors such as smoking, long-term use of oral contraceptives, and immunosuppression—including HIV infection—increase the risk of progression. For those diagnosed, treatment options range from surgery and radiation to immunotherapy, but outcomes depend heavily on the stage of detection, which is categorized by the 2018 FIGO system.
