AI models trained on Sweden’s national registry data have shown promising results in identifying individuals at higher risk of melanoma, achieving 73% accuracy and paving the way for personalized screening strategies.
New Delhi, Apr 15: Artificial intelligence (AI) is emerging as a powerful tool in healthcare, with a new study from Sweden demonstrating its potential to identify early risk patterns for melanoma, the most serious form of skin cancer. Conducted by researchers at the University of Gothenburg’s Sahlgrenska Academy, the study analysed registry data covering the entire adult population of Sweden, totalling more than 6 million individuals.
The dataset included age, sex, medical diagnoses, medication use, and socioeconomic factors. Over five years, 38,582 individuals (0.64 percent) developed melanoma. By applying advanced AI models to this data, researchers were able to distinguish individuals who later developed melanoma from those who did not with an accuracy of about 73 percent. This was a significant improvement compared to traditional methods that rely only on age and sex, which achieved around 64 percent accuracy.
Importantly, the combination of medical history, medication records, and sociodemographic data allowed the identification of small, high-risk groups. For these groups, the risk of developing melanoma within five years was as high as 33 percent. According to doctoral student Martin Gillstedt, this demonstrates that existing healthcare registry data can be strategically leveraged to identify individuals at higher risk, paving the way for more personalized monitoring.

Associate Professor Sam Polesie emphasised that selective screening of these high-risk groups could lead to more efficient use of healthcare resources and more accurate monitoring. While this form of AI-driven decision support is not yet available in routine healthcare, the findings highlight the potential of integrating population data into precision medicine.
The study underscores the importance of further research and policy development before such methods can be widely implemented. However, it provides a clear signal that AI models trained on large-scale registry data could become a vital tool in future screening strategies, offering more personalized risk assessments and potentially saving lives through earlier detection of melanoma.
