A rising number of women have never been screened for cervical cancer. Here are the risks

Why More Women Are Skipping Cervical Cancer Screening

Earthguardiansonline.com – A rising number of women have never received a cervical cancer screening, according to a new analysis that tracks two decades of national survey data. Published on August 27 in JAMA Network Open, the study draws on responses from more than 106,000 women collected through the CDC’s nationally representative survey between 2005 and 2023. The headline finding: among young women eligible for screening, the share reporting zero lifetime checks nearly tripled over that span, moving from roughly one in eight to close to one in three.

The Scale of the Gap

For women aged 21 through 29, the never-screened proportion climbed from 12.5 percent in 2005 to approximately 32 percent by 2023 — a figure that translates into roughly 6.2 million young Americans who have never had a single cervical check. Among women aged 30 to 65, the comparable share rose from 5.3 percent to nearly 15 percent, representing about 9.2 million additional women without a screening history. A rising number of women in both age brackets are therefore missing a preventive step that could detect precancerous changes years before they progress to invasive disease.

The shortfall is unevenly distributed across demographic lines. In 2023, about 44 percent of Asian women aged 21 to 29 reported no prior screening, compared with roughly 29 percent of White women in the same bracket. Education amplified the divide: young women whose highest credential was a high-school diploma were nearly twice as likely to have skipped screening (around 39 percent) as those holding a master’s or doctoral degree (approximately 17 percent). Insurance status compounded the problem for older women; nearly 32 percent of uninsured women aged 30 to 65 had never been screened, versus 11 percent of those with private coverage.

Why Untreated HPV Becomes Cancer

More than nine out of ten cervical cancers originate from a persistent infection with high-risk strains of human papillomavirus, a virus transmitted through routine intimate skin-to-skin contact. In most people the immune system clears the virus without lasting effect. In a smaller subset, however, the infection endures and drives abnormal changes in cervical cells. Those changes follow a slow trajectory from precancerous lesion to invasive malignancy — a window during which a Pap test or HPV test can identify the problem and allow it to be monitored or removed before it becomes cancer.

Dr. Leana Wen, an emergency physician and clinical associate professor at George Washington University who previously served as Baltimore’s health commissioner, framed the stakes for CNN:

“Women who have never been screened have missed this opportunity entirely. The authors make the point that establishing screening among young adults can also set the pattern for preventive care later in life, when cervical cancer risk is higher.”

The HPV vaccine, available for both sexes, can cut the incidence of certain HPV-linked cancers by roughly half. Vaccination, however, does not replace periodic screening. Women who were vaccinated before the virus became endemic, or who were never vaccinated at all, still need regular checks to catch residual or new cellular abnormalities.

What the Data Cannot Confirm

Wen flagged several important caveats. Because screening history was self-reported, respondents may have misremembered whether or when they were last examined. The survey also cannot establish causation: researchers observed that among women aged 30 to 64, rates of later-stage cervical cancer climbed by more than two percent per year after 2017, and that women 65 and older likewise saw rising rates of more advanced disease. Those trends are alarming, but the data cannot confirm that reduced screening is the driver rather than a parallel symptom of broader access problems.

Possible explanations for the decline span a wide range — inadequate insurance coverage, geographic or financial barriers to care, discomfort with the procedure itself, and simple unawareness about when screening should begin and how often it should repeat. Disentangling those factors requires further research.

How Screening Actually Works

Two principal methods form the backbone of cervical cancer screening. The Pap test collects a small sample of cells from the cervix using a spatula or brush, then examines those cells under a microscope for precancerous or malignant changes. HPV testing, by contrast, detects the genetic material of high-risk HPV strains directly, often through a vaginal swab. Depending on age and prior results, a clinician may recommend one test, the other, or both at defined intervals.

Frequently Asked Questions

How often should I get screened? Current U.S. guidelines generally recommend a Pap test every three years, or a combined Pap-plus-HPV test every five years, for women aged 21 through 65. Your clinician can tailor the schedule to your individual history.

Does the HPV vaccine mean I no longer need screening? No. Vaccination lowers risk substantially but does not eliminate it, particularly for strains not covered by the vaccine or for infections acquired before vaccination. Periodic screening remains recommended.

What if I’ve never been screened and I’m over 30? Schedule an appointment as soon as practical. A single Pap or HPV test can identify existing abnormalities, and early detection dramatically improves outcomes.

Is screening painful? Most women report only mild discomfort. The procedure takes a few minutes and requires no special preparation beyond avoiding vaginal products for 48 hours beforehand.
