England’s national lung cancer screening programme has reached a major milestone, with newly published data showing substantial uptake, wide coverage and signs that more cancers are being found at an earlier stage. The findings, published in Nature Medicine, track the programme from its launch in 2019 through March 2025 and suggest the initiative is beginning to reshape lung cancer detection across the NHS in England.

More than 2.5 million invitations issued
According to the study, 2,510,092 people had been invited for a baseline Lung Health Check across all Cancer Alliances in the whole-programme data from April 2019 to March 2025. That represents 32.4% of the estimated eligible population of people who have ever smoked, aged 55–74. Of those invited, 49.0% completed a Lung Health Check, and 43.0% underwent a baseline low-dose CT scan. ([nature.com](https://www.nature.com/articles/s41591-026-04292-y))
The programme, initially launched as the Targeted Lung Health Check Programme before being renamed the NHS England Lung Cancer Screening Programme on 1 February 2025, was designed to improve the proportion of cancers detected at stage 1 and 2 and to provide real-world evidence for wider rollout. The study says the early pilot work demonstrated that screening was feasible and capable of identifying more cancers at an earlier stage than previous approaches.

Evidence points to earlier diagnosis
The authors report that the screening programme has already shown an impact on the early-stage proportion in national lung cancer registry data, which has risen as screen-detected lung cancer has increased. The paper also notes that no similar trend has been seen in other cancers in England, strengthening the case that the programme itself is driving the change.

In practical terms, the programme has created a structured pathway for identifying high-risk individuals, offering lung health checks and directing eligible participants to imaging and follow-up where needed. The study also highlights that most Lung Health Checks were delivered by telephone, with face-to-face confirmation used for those who qualified for CT screening.

Why the findings matter for the NHS
The research arrives at a time when the NHS is under pressure to improve cancer outcomes through earlier diagnosis and more efficient use of screening resources. The paper states that the programme was intended to inform commissioning budgets for full rollout and to support a national strategic, clinical and economic framework for deployment. ([nature.com](https://www.nature.com/articles/s41591-026-04292-y))
The broader significance is clear: lung cancer remains one of the most serious cancer challenges, and the ability to identify disease before symptoms progress can improve the chance of treatment at a more manageable stage. While the study does not claim the programme has solved the problem, it does show that large-scale screening can be delivered across England at national scale and can produce measurable early-detection gains. ([nature.com](https://www.nature.com/articles/s41591-026-04292-y))
As screening expands, the next questions will focus on sustained uptake, equitable access and how quickly the programme can continue translating earlier detection into better outcomes for patients. For now, the five-year data provide one of the clearest signals yet that England’s lung cancer screening strategy is gaining traction.
