In The Hague, professor of Sociology of Technology and Innovation Chris Snijders launched the app OddSpot, which can determine if a speck on your skin could be early-stage skin cancer. By request of the Dermatology department of the Eindhoven Catharina Hospital, which is flooded with worried people, he developed a survey that determines if a certain spot is ‘actinic keratosis’ or ‘basal cell carcinoma’ – two of the most common precancerous stages of skin cancer – with an accuracy of 90 to 95 percent. The 89-cent app is available for iPhone and Android and it’s nearly as good as a dermatologist and much better than a family doctor when it comes to diagnosis, according to Snijders.
