According to MedGadget:
"Yanko, the design blog we highlight occasionally, shows us a device design by Antonia Haaf meant to automatically detect melanoma, called Black Skin Cancer. Details are vague, as they usually are with concept designs, but the device is meant to be placed over a suspected legion and, "[analyze] 2D and 3D characteristics from melanocytic lesions with just one shot. Using a secret algorithm, the device recognizes critical lesions such as the nodular melanome."
While pretty, commenter Widepers on the site points out, "frankly a magnifying glass and the skin-doctor's email might do the trick just as well."
