Researchers from King’s College London estimate that more than one million additional women could receive life-saving cervical cancer screenings if the NHS implemented self-testing methods.
The results of their trial, which focused on do-it-yourself testing, were described as “fantastic” and empowering for women.
These home testing kits, similar to Covid swabs but longer, are sent to a lab for analysis.

The NHS found the trial’s outcomes extremely encouraging and is currently considering a broader rollout. Each year, the UK sees over 3,000 new cases of cervical cancer.
The cervix, which connects the top of the vagina to the womb, is screened regularly to detect potential cancerous changes.
Despite invitations for screening every three to five years for women aged 25 to 65, around 4.6 million women in England do not participate.
Mairead Lyons, a senior consultant on the trial, explained that cervical cancer screening rates have been declining for two decades, often because women find the experience uncomfortable, or they feel too busy, embarrassed, or afraid.
The YouScreen trial marked the first UK instance of self-testing in cervical cancer screening. Participants received the kit in two ways: through an automatic offer by their GP if they were six months overdue, or by mail if they were 15 months overdue.
The kit includes a long cotton swab for a vaginal lining sample, which is then tested for human papillomavirus (HPV), the primary cause of cervical cancer.
A positive result leads to further testing to check for precancerous cells. The trial, conducted in five London boroughs in 2021, offered 27,000 test kits, with 56% of GP-offered kits and 13% of mailed kits completed.
If implemented nationwide, researchers predict this method could raise screening rates from 69.9% to 77.3%, adding approximately one million women to the three-year screening cycle. The trial also demonstrated that self-testing reached women across various ethnic and economic backgrounds.
Dr. Anita Lim from King’s College London called self-testing a “game-changer” for cervical screening, with evidence from the UK population to support its efficacy. Self-testing is already available in countries like Australia, the Netherlands, Denmark, and Sweden.
Deborah Tomalin, NHS England’s screening and vaccination director, praised the trial’s findings and indicated the NHS would work with the UK National Screening Committee to explore wider implementation.
The HPV vaccine has already significantly reduced cervical cancer rates by nearly 90%. Professor Peter Sasieni, also involved in the trial, noted that young women vaccinated against HPV in childhood might only need one to three lifetime screenings.
However, no changes to the screening program for vaccinated women have been made, so the current advice remains to attend screenings when invited.
Regular screening remains crucial for women born before 1990, who are less likely to benefit from the HPV vaccine.
Key symptoms of cervical cancer include unusual vaginal bleeding, changes in vaginal discharge, pain during sex, and discomfort in the lower back, abdomen, or pelvis.
