A hospital in west London is harnessing the power of Artificial Intelligence (AI) to transform skin cancer checks, speeding up diagnoses and reducing patient wait times.
Chelsea and Westminster Hospital has become the first in the UK to implement an AI system that can accurately rule out skin cancer in minutes, allowing thousands of patients to receive rapid reassurance without needing to see a doctor.
How It Works
The AI tool, developed by UK-based Skin Analytics, analyses images of suspicious moles and lesions with 99% accuracy in identifying benign cases. Medical photographers capture the images using an iPhone equipped with the DERM app, which are then transferred to a desktop for deeper analysis.
Patients with harmless moles are quickly discharged, while those requiring further investigation are fast-tracked to specialists. This innovation has significantly reduced the burden on dermatologists, enabling them to focus on high-risk cases.
A Game-Changer for NHS Patients
With 7,000 urgent skin cancer referrals1 each year—only 5% of which turn out to be cancerous—the hospital was struggling to keep up with demand.
Dr. Louise Fearfield, a consultant dermatologist, said: “Without this technology, we wouldn’t be able to manage the volume of urgent referrals. Patients would face delays, and some might even be missed.”
One patient, Jimmy Tovey, sought an AI check after his brother was diagnosed with melanoma. “They took a picture, and within two days, I was told it was nothing to worry about. All the stress was gone,” he shared.
Expanding Across the NHS
The success of the AI system has led to its adoption in over 20 NHS hospitals, where it has helped detect more than 14,000 cancer cases.
Roger Chinn, Chief Medical Officer at Chelsea and Westminster Hospital NHS Foundation Trust, emphasized the impact: “Waiting for a diagnosis can be incredibly stressful. This is a major step forward in improving efficiency and patient care.”
The Future of AI in Dermatology
Experts believe the next frontier is at-home AI diagnostics. Dr. Lucy Thomas, another consultant dermatologist, noted: “The goal is to bring this technology closer to patients. While current limitations exist—such as the need for specialized lenses—advancements will soon make self-checks possible.”
As AI continues to evolve, its role in healthcare promises faster, more accurate diagnoses—ultimately saving lives and easing the strain on medical professionals.
