The National Cancer Plan promised new radiotherapy machines would treat 27,500 more patients a year. Five months after publication, a correction quietly turned those patients into treatments.
Estimated reading time: 6 minutes
In short. The National Cancer Plan for England said its £70 million investment in new radiotherapy machines would deliver "27,500 more patients to receive treatment annually" (page 15) [2]. Its own cited source, a May 2025 press release, said "up to 27,500 additional treatments per year" [3], not patients. A correction slip dated 8 July 2026 brought the plan's text into line [2]. The plan's proof that progress is "already happening" also carries two different numbers on two different pages, and its delivery table needed correcting on its own first target year within a fortnight of publication. Three documented mistakes: four stars.
A £70 million claim that outran its own source
The National Cancer Plan for England was published on 4 February 2026, presented to Parliament by the minister for public health [1]. Among its headline claims for progress already delivered: "This government has invested £70 million to deliver 28 new radiotherapy machines. These will replace outdated machines and will deliver 15% more treatments" (page 15) [2]. That sentence is footnoted to a Department of Health and Social Care press release, "Faster cancer treatment thanks to new radiotherapy machines" [2].
That press release, published 26 May 2025, says the machines will deliver "up to 27,500 additional treatments per year" [3]. A radiotherapy treatment is usually one of several fractions delivered to the same patient over a course of care, not one patient seen once. Treatments and patients are different units, and the Plan as first published collapsed them: it told readers the £70 million would mean "27,500 more patients to receive treatment annually," a claim its own cited evidence did not make.
A correction slip attached to the document, dated 8 July 2026, fixes it. Under the heading "Page 15 - final paragraph, second sentence," it records: "Text currently reads: ... allowing 27,500 more patients to receive treatment annually. Text should read: ... allowing 27,500 more treatments annually" [2]. Filed five months after publication as a correction rather than flagged anywhere in the plan's own text as a downgrade, it brings the sentence back to what the department's own source said in May 2025. If a radiotherapy course runs to a dozen or more fractions, 27,500 treatments could mean a small fraction of 27,500 patients actually benefiting each year, not the headcount the plan first claimed.
Two numbers for the same 'already working'
The plan makes a second claim of its own progress, used to justify the case for the radical change that follows. The Secretary of State's foreword states it first: "Over 212,000 more people are getting a diagnosis on time, around 37,000 more are starting treatment on time, and rates of early diagnosis are hitting record highs" (page 2) [2]. Seven pages later, the executive summary states what reads as the same underlying claim with different numbers: "In the year to March 2025, over 227,000 more people received a diagnosis on time and 38,000 more people started treatment on time than the previous year" (page 9) [2].
Neither passage carries a footnote to NHS England's cancer waiting times statistics or any other source a reader could check against. That leaves two different headline figures for what the document itself presents as its central proof that "progress is possible because it's already happening" (page 2) [2], inside the same 87-page publication, with no reconciliation between the two.
A delivery table corrected within a fortnight
The plan's substance sits in year-by-year delivery tables running to more than 30 numbered actions, each assigned a responsible body and a target year between 2026 and 2029. The first of these to need fixing was Action 7, on palliative and end of life care. The original text read: "Next year, we will publish a Modern Service Framework on Palliative and End of Life Care to address these challenges," with the delivery table's timeframe column giving "2027" (page 49 and page 53) [2].
A correction slip dated 17 February 2026, less than a fortnight after the plan's 4 February publication, changed both: "Text should read: This year, we will publish a Modern Service Framework," and the table's timeframe corrected from "2027" to "2026" [2]. The current text reflects the fix throughout. It is a small error in isolation, one action's target year out of more than 30. But it is the very first specific date the document commits to, and it was wrong when the plan first went to print. The other 29 dated commitments in the same tables have not needed a public correction; whether that is because they were checked more carefully, or simply have not been tested yet, the document does not say.
The claims, tested
| The claim | What the record shows | Verdict |
|---|---|---|
| New radiotherapy machines will mean "27,500 more patients to receive treatment annually" (page 15, as first published) [2] | The plan's own cited source says "up to 27,500 additional treatments per year" [3], not patients; a correction slip dated 8 July 2026 changed the plan's wording to match [2] | The original claim overstated the investment's reach against its own evidence, and was corrected only five months later |
| "Over 212,000 more people are getting a diagnosis on time, around 37,000 more are starting treatment on time" (page 2) [2] | The executive summary states "over 227,000 more people received a diagnosis on time and 38,000 more people started treatment on time" for "the year to March 2025" (page 9) [2] | Two different figures for what reads as the same proof point, neither footnoted to a checkable source |
| Action 7's original timeframe: "Next year" and "2027" (pages 49 and 53, as first published) [2] | Corrected 17 February 2026, less than a fortnight after publication, to "This year" and "2026" [2] | The plan's first specific delivery date was wrong when printed |
Credit where due
Set against 87 pages and more than 30 dated commitments, three corrected or unreconciled figures is not evidence of a plan built on false claims. Most of the document's numbers carry a working footnote a reader can follow, including the 68% current histopathology performance against a 98% target that the plan states candidly rather than obscures (page 13) [2], and the headline 2035 survival ambition, three in four people diagnosed surviving five years, is explicitly benchmarked against a cited projected baseline of 60% in 2022 and 50% in 2008, not asserted without a yardstick (page 23) [2]. The department has also published its corrections openly, as a permanent slip attached to the document, rather than silently editing the PDF and leaving no trace.
Three documented mistakes. (1) The plan's claim that £70 million of new radiotherapy machines would mean "27,500 more patients" receiving treatment overstated its own cited source, which said 27,500 additional treatments; corrected five months after publication. (2) The plan's proof that progress is "already happening" gives one set of figures in the foreword (212,000 / 37,000) and a different set in the executive summary (227,000 / 38,000), neither sourced to a footnote. (3) The delivery table's first dated commitment, the Palliative and End of Life Care Modern Service Framework, needed its target year corrected from 2027 to 2026 within a fortnight of publication. Rated four stars out of five.
