Skin Cancer Detection Apps: Accuracy Concerns and What to Know

Artificial intelligence (AI)-powered smartphone applications designed to support individuals assess skin lesions for potential skin cancer are gaining popularity, with some even being offered through health insurance plans. However, recent research raises concerns about their accuracy, highlighting both the potential for missed diagnoses and false alarms.

Study Findings: Missed Cancers and False Positives

A study conducted by researchers at UZ Gent and Ghent University in Belgium, analyzing data from 2021-2023, evaluated the performance of the SkinVision app compared to assessments by dermatologists. The findings, published in February 2026, revealed significant limitations. The app was unable to assess 16-19% of photos due to factors like hair, location in skin folds, or lack of pigmentation .

Among the lesions that could be assessed, the app provided incorrect advice in 15% of cases. Specifically, approximately 1 in 8 benign (non-cancerous) lesions triggered a false positive alarm, whereas roughly 1 in 4 actual skin cancers were missed . When patients took the photos themselves, the percentage of unusable images rose to 71%.

How SkinVision Works and Its Limitations

SkinVision operates by allowing users to photograph a skin lesion, which is then analyzed by an AI algorithm to determine if it appears suspicious. Users can also consult with a teledermatologist for further evaluation. The app has over 3 million users worldwide and performed 100,000 checks in 2025 in Belgium alone .

SkinVision acknowledges the study’s findings are based on older data and states that its AI algorithm has been updated since the research was conducted. The company emphasizes that the app is intended as a screening tool, not a diagnostic replacement and that image quality and patient selection can influence results .

Expert Skin Cancer Care at UCLA Health

For comprehensive skin cancer care, specialized centers like UCLA Health offer a multidisciplinary approach involving dermatologists, medical oncologists, radiation oncologists, surgical oncologists, and nuclear medicine specialists . They provide individualized treatment plans, access to innovative research, and expertise in treating all types of skin cancer, including rare cases .

Vital Considerations and Next Steps

If a skin cancer detection app indicates a suspicious lesion, it is crucial to promptly consult with a healthcare professional – a dermatologist or primary care physician – for a proper diagnosis. Conversely, a reassuring result from the app should not delay a medical evaluation if you have ongoing concerns about a skin lesion.

Several health insurance funds in Belgium offer (partial) reimbursement for the SkinVision app, underscoring its increasing integration into healthcare systems. However, the recent research highlights the necessitate for cautious interpretation of the app’s results and the importance of professional medical follow-up.
