NHS to bring ‘sponge-on-a-string’ cancer test to the high street
A new way to detect cancer early
NHS England is introducing the Cytosponge test - also known as the ‘sponge-on-a-string’ - outside hospitals for the first time. Soon, you’ll be able to have this test done at your local pharmacy, GP surgery, or even a pop-up clinic, saving you time and the hassle of hospital visits.
Here’s how it works: you swallow a small capsule attached to a string. Once it reaches your stomach, the capsule dissolves, and the sponge expands. A nurse then gently pulls the sponge back up, collecting cells from your oesophagus (food pipe) for testing. It takes just 10 minutes, no sedation is needed, and you can go straight home.
This test helps find Barrett’s oesophagus, a condition caused by long-term acid reflux that can develop into oesophageal cancer if untreated. Since many people don’t notice symptoms early on, this test offers a valuable chance to detect cancer before it becomes serious.
Voices behind the test
Professor Peter Johnson, NHS England’s National Clinical Director for Cancer, says:
"The sponge-on-a-string test is a game changer. It’s quick, non-invasive, and could help us spot signs of cancer much earlier—when it’s far easier to treat."
Eddie, 77, from Suffolk, who credits the test with potentially saving his life after years of heartburn, shared:
"I was quite nervous but it was so simple. Thanks to the test, they found Barrett’s oesophagus early, and I got treatment quickly."
Minister for Public Health and Prevention Ashley Dalton said:
"Making this test available in your community means earlier diagnosis and treatment, which can save lives."
Marcel Gehrung, Co-founder and CEO of Cyted Health, explained:
"This innovative test reflects how technology can transform healthcare, making cancer detection faster and less invasive."
What’s next?
- NHS England has already run successful pilots of the test in GP surgeries and community clinics, with patients finding it easier and more comfortable than traditional endoscopies.
- If you have had acid reflux or related symptoms for a long time, you may be invited to take the test in the future. The goal is to bring testing closer to you, reducing wait times and travel.
Looking ahead — together
NHS England is changing how care reaches you making cancer testing quicker, easier, and more local. If you’re invited to take the Cytosponge test, it could be a small step that makes a big difference. Early detection means more time, better treatment options, and peace of mind.
