MORE THAN ONE million extra women could undergo life-saving cervical cancer screenings if the NHS adopts do-it-yourself (DIY) testing, researchers estimate. The team at King’s College London, which conducted the self-testing trial, described the results as “fantastic” and noted that it “gave power to women.” The kits resemble a longer version of a Covid swab and are sent to a lab for analysis.
The NHS has praised the findings as extremely positive and is currently evaluating whether to implement the scheme nationwide. Each year, more than 3,000 new cases of cervical cancer are diagnosed in the UK. The cervix, a small opening that connects the top of the vagina to the base of the womb, is the site where these cancers develop.
The Problem with Traditional Screening
Women in the UK are invited for cervical cancer screening, traditionally known as the smear test, every three to five years between the ages of 25 and 65. Despite this, approximately 4.6 million women in England—nearly a third of those eligible—do not participate in the screenings.
“Cervical cancer screening has been in decline for the last 20 years,” said Mairead Lyons, a senior consultant involved in the trial. “Many women will describe it as an uncomfortable experience, or they are too busy, embarrassed, or afraid of the physical experience of it.”
The YouScreen Trial
The YouScreen trial represents the first instance of self-testing being offered as part of cervical cancer screening in the UK. Women and people with a cervix were given self-testing kits through two methods:
- If they were six months overdue for screening and visited their GP for any reason, their doctor was automatically alerted and offered them a kit.
- If they were 15 months overdue for screening, a kit was sent to their home address.
The kit (picture above) includes a long cotton-wool bud used to swab the lining of the vagina for about 20 seconds. The sample is then sent to a laboratory to test for human papillomavirus (HPV), the primary cause of most cervical cancers. If the test is positive, the individuals are invited for a further test to determine if any cells in the cervix have started to become cancerous.
In 2021, the trial was conducted across five London boroughs, with 27,000 test kits distributed. According to results published in eClinicalMedicine:
- 56% of those offered tests by their GP completed them.
- 13% of those sent tests by mail completed them.
Extrapolating these results across England, researchers estimate that this approach could increase the screening rate from 69.9% to 77.3%—about one million extra women over a three-year screening cycle. The trial also demonstrated that self-testing reached women regardless of their ethnicity or socioeconomic status.
Reactions and Future Implications
“I am so excited by it,” said Lyons. “I’ve spent over 30 years in the health service, and this is fantastic.” Dr. Anita Lim from King’s College London added, “Self-sampling has been hailed as a game-changer for cervical screening, and we now have evidence in a UK population to show that it really is.”
Self-testing is already available in countries like Australia, the Netherlands, Denmark, and Sweden. NHS England’s Screening and Vaccination Director, Deborah Tomalin, called the trial results “extremely promising,” adding that the NHS would work with the UK National Screening Committee to explore the feasibility of a broader rollout across England.
The Role of HPV Vaccination
While the self-testing kits offer a promising advance in screening, the HPV vaccine is also significantly reducing cervical cancer rates. The vaccine is credited with cutting cervical cancer by nearly 90%. Prof. Peter Sasieni, who also participated in the self-testing trial, noted that young women vaccinated against HPV in childhood might only need one to three cervical cancer screenings in their lifetime.
However, for women born before 1990 who are unlikely to benefit from the vaccine, regular screening remains crucial. Prof. Sasieni emphasized the importance of attending screenings when invited.
Symptoms of Cervical Cancer
Understanding the symptoms of cervical cancer is vital for early detection and treatment. Main symptoms include:
- Vaginal bleeding that’s unusual for you, including during or after sex, between periods, after menopause, or heavier periods than usual.
- Changes to vaginal discharge.
- Pain during sex or in the lower back, lower abdomen, or between the hip bones (pelvis).
Conclusion
The introduction of DIY cervical cancer testing kits could significantly enhance screening rates, empowering more women to take control of their health. Coupled with the HPV vaccine, this approach holds promise for reducing cervical cancer incidence and ensuring earlier detection and treatment. As the NHS evaluates these findings, the potential for a wider rollout could mark a significant advance in women’s health care.
