Wales radiologist shortage is delaying cancer scans and changing bedside decisions
Cancer care in north and west Wales is being strained by a radiology workforce gap large enough to affect diagnosis, follow-up, and the emotional stability of patients already living with active disease. The Royal College of Radiologists says NHS Wales is 88 radiologists short of need, a 28% deficit, and for the first time it has seen patients whose conditions are deteriorating while they wait for scans and test results.
For people with cancer, imaging is not a routine administrative step. It is the mechanism that tells clinicians whether a treatment is still holding disease in check, whether a mass is growing again, or whether a new symptom represents progression rather than treatment effect. When scans are delayed, the clinical picture stops being current. In oncology, that can mean a window for intervention narrows before anyone realizes the disease has changed.
Beverly Scott has lived with that uncertainty for 14 years after being diagnosed with ovarian and peritoneal cancer. She was given five years to live at the time of diagnosis, later entered trials at the Royal Marsden Hospital in London, and has remained stable on ongoing treatment. Her experience reflects why imaging matters so much in long-term cancer management: a stable course depends on repeated confirmation that the disease has not advanced beyond what treatment can suppress. “You are anxious to know has the cancer spread,” she said, describing the mental burden while waiting for results.
Waiting can be clinically dangerous as well as emotionally punishing.
Scott said delays in scans could allow cancer to spread unnoticed and leave treatment choices less effective. That concern is biologically plausible. Ovarian and peritoneal cancers can progress quietly, and imaging often determines whether therapy continues unchanged, needs escalation, or has failed altogether. Without timely radiology reporting, a patient can remain on a regimen that is no longer enough, while the disease advances in the background.
Karen Jones, who was first diagnosed with breast cancer in 2015, later developed colon cancer and then had her breast cancer return in 2021, described the wait for results as “terrible, horrific and horrendous.” Her words capture the psychological strain of survivorship in a system where surveillance is part of treatment. For patients with prior recurrences, each scan carries a direct question: has the disease returned again, or is stability holding? A delay does not merely postpone reassurance. It postpones the moment when a new therapeutic decision can be made.
The staffing problem is most severe in parts of Wales already under pressure. North and west Wales have a 42% shortfall in consultant radiologists, compared with 22% in south Wales, based on the Royal College of Radiologists’ 2025 clinical radiology census. In 2024, the radiology workforce in Wales grew by only 1.1%, well below the UK average of 5%. That slow growth matters because radiology demand has risen sharply, especially for cancer imaging, where every additional referral, surveillance scan, and urgent test adds to the backlog.
Radiologists sit at the center of a chain that starts with suspicion and ends with treatment planning. When the reporting queue lengthens, cancer pathways become slower at every stage. Surgery may be deferred because staging is incomplete, oncology appointments may be cancelled because no report is available, and patients may be left in limbo while clinicians wait for information that should already be in hand. Dr Owen Nicholas, a consultant oncologist in Swansea and chair of the Welsh committee for the Royal College of Radiologists, said the shortage is now affecting patients directly. He described the difficult moment when a clinician must tell an anxious patient that the report is not yet available, or cancel an appointment because the scan has not been read.
Betsi Cadwaladr health board, which covers one of the worst-affected areas, says recruitment is ongoing and that reporting times have improved despite a substantial increase in demand for scans. Clara Day, the board’s executive medical director, said the figures are concerning for patients and pointed to active recruitment into both radiology and oncology. She also described a strategy that includes nurse-led clinics and metastatic nurse specialist teams for colorectal and breast cancer, along with closer links to the North Wales Medical School to support workforce development.
Those service changes may help buffer pressure, but they do not erase the underlying shortage. The board says robust arrangements are in place to prioritise patients according to clinical need and to maintain safe services. It also says a third-party imaging provider has helped reduce waiting times for scans and results since April, with reporting times closely monitored. In practical terms, that suggests a system trying to absorb demand through redistribution, outsourcing, and triage rather than through a fully staffed internal workforce.
The stakes are clearest in patients whose disease can worsen silently between scans. For them, radiology is not a background service; it is the surveillance tool that keeps treatment honest. When that tool falters, the first sign of progression may come later, and later means fewer options.
The unresolved issue is how quickly Wales can close a workforce gap that has already reached the point where clinicians are seeing deterioration while patients wait for diagnostic answers.
