Nearly one in three young women in the U.S. aged 21 to 29 had never been screened for cervical cancer by 2023, according to an analysis of federal health data published in JAMA Network Open. The study, led by researchers from the Medical University of South Carolina, found that the share of never-screened young women jumped from roughly 12.5% in 2005 to 31.9% by 2023. Public health researchers warn that this widening prevention gap coincides with climbing rates of advanced-stage cervical cancer diagnoses among women in their 30s and older, raising alarms about missed early detection opportunities.
How Researchers Tracked Cervical Cancer Screening Trends
To measure shifts in preventative care, study authors combed through national health survey data collected between 2005 and 2023, alongside federal cancer registry records. The team evaluated responses from more than 106,000 women surveyed through the National Health Interview Survey, adjusting figures to exclude individuals who had undergone a hysterectomy. Researchers also monitored human papillomavirus (HPV) vaccination rates and compared those metrics against cervical cancer case data spanning from 2001 to 2023. According to the study, the data reveals a prevention system losing traction among younger generations just as they enter the target age range for routine checks.
The Numbers Behind the Screening Decline
The share of women aged 21 to 29 who had never received a cervical screening climbed sharply from 3.5 million individuals in 2005 to 6.2 million in 2023. Older demographics experienced a similar trajectory. Among women aged 30 to 65, the never-screened rate grew from 5.3% in 2005 to 14.8% in 2023, leaving roughly one in seven women in that broader group entirely unexamined, based on federal survey estimates. While HPV vaccination rates among the youngest cohort rose from 5.7% in 2008 to 54.0% in 2019, authors noted that nearly 8 million young women remained unvaccinated, and about a third of those unvaccinated individuals had also never been screened.
Demographic Disparities in Preventative Care
Skipping screenings does not affect all populations equally. In 2023, never-screening rates reached 44.3% among Asian women aged 21 to 29, compared to 28.8% for White women in that same age bracket, according to the JAMA Network Open analysis. Educational attainment also played a major role: 39.0% of young women with only a high school diploma had never been screened, versus 17.1% of those holding a master’s or doctoral degree. Among older women aged 30 to 65, additional barriers emerged, with uninsured individuals and those living in the South and Northeast reporting higher rates of never being screened than their insured or Western counterparts.
Rising Rates of Advanced-Stage Diagnoses
Alongside the drop in routine screenings, national cancer registry data showed that cervical cancer cases diagnosed at an advanced stage—where the disease has spread beyond the cervix—have increased by more than 2% per year starting in 2017 for women aged 30 to 64. For women aged 65 and older, advanced cases have climbed steadily since 2001. While study authors emphasized that the data does not directly prove a causal link between missed screenings and late-stage diagnoses, they characterized the trend as a concerning overlap that warrants urgent public health attention.
Frequently Asked Questions
What causes the increase in advanced cervical cancer cases?
Researchers note that while the study does not definitively prove causation, the rise in advanced-stage diagnoses among women aged 30 to 64 coincides with a significant upward trend in women reaching adulthood without ever receiving a cervical cancer screening.
Which groups are most likely to skip cervical cancer screenings?
According to the federal health data, never-screening rates are highest among Asian women, individuals with lower formal education levels, uninsured women, and residents of the South and Northeast regions.
What is involved in a cervical cancer screening test?
A provider uses a speculum during a pelvic exam to view the cervix and collects a small cell sample using a soft brush. The sample is then tested for cancer-causing HPV strains or abnormal cellular changes.
Does the HPV vaccine replace the need for cervical cancer screenings?
No. Public health researchers emphasize that vaccination and screening serve as dual layers of protection, noting that many unvaccinated young women in the study were also missing routine screenings.
