An AI Skin Tool That Explains Itself Spotted Nearly 94 Percent of Skin Cancers

Mayo Clinic researchers reported Oct. 22 in Mayo Clinic Proceedings that DEXI, an imaging tool that scores skin lesions from 0 to 10, correctly identified almost 94 percent of skin cancers and ruled out about 75 percent of non-cancerous lesions across 261 lesions in 178 patients. Unlike a black-box score, DEXI shows which features such as asymmetry, border and color drove its rating, giving dermatologists a usable threshold for deciding between monitoring and biopsy. The team cautions it still needs validation and must be read alongside clinical findings.
