The National Health Service has introduced a new genomic testing method designed to significantly accelerate brain tumour diagnosis. The test analyzes the genetic code of tumour tissue samples and can deliver results in approximately two hours, compared to the traditional timeline of up to eight weeks for complete diagnostic information.
The technology uses a sequencing machine manufactured by Oxford Nanopore, combined with specialist software developed at the University of Nottingham in collaboration with hospital clinicians. DNA molecules pass through a nanopore—a microscopic opening—to reveal the tumour’s unique genomic fingerprint. In one documented case, results were available after the sequencing machine ran for 20 minutes. This rapid turnaround allows surgeons to receive diagnostic information while patients remain on the operating table, potentially enabling real-time decisions about surgical strategy.
The pilot programme involves five specialist centres located in Nottingham, Birmingham, London, and Newcastle, with planned expansion to Bristol, Oxford, Leeds, and Manchester. According to NHS England officials, this represents a world-first rollout of the technology across multiple hospitals. The testing approach enables more precise tumour classification than traditional microscopic examination, providing clinicians with comprehensive molecular data rather than relying on visual analysis alone.
Approximately 12,000 individuals in the UK receive a primary brain tumour diagnosis annually. The condition represents the leading cancer cause of death among children and adults under 40. NHS leaders describe the rapid diagnostic capability as potentially transformative, as faster diagnosis enables patients to access appropriate treatment or clinical trials sooner. The genomic profile obtained through testing also facilitates more rapid access to clinical trial opportunities for patients. The pilot builds on earlier diagnostic work already underway in Nottingham and Birmingham.
