New AI skin cancer tool detects 93% of cancerous lesions
An artificial intelligence tool identified more than 93% of cancerous skin lesions in a Mayo Clinic study, suggesting it could provide another useful signal when dermatologists decide whether a suspicious spot needs a biopsy. The system, called Dermoscopy Explainable Intelligence or DEXI, examines detailed images of skin lesions. It assigns a score from zero to ten based on features linked to cancer risk. Unlike a simple risk label, DEXI also highlights image characteristics that influenced its score, such as a lesion’s shape, border and color. That explanation may help doctors interpret the result. The research, published in Mayo Clinic Proceedings, reviewed records from 178 patients who underwent detailed skin imaging and later had one or more lesions examined through a biopsy. The team analyzed 261 lesions with both an AI score and a diagnosis confirmed by tissue examination. This…
