She lost her mother to cancer after a misdiagnosis. At 16, she built an AI system to prevent the same thing from happening to others. Melek Öztürk was 16 when her mother was first misdiagnosed with pancreatic cancer, then correctly identified with adrenal gland cancer. The delays and confusion during treatment showed her firsthand how much damage a wrong diagnosis can do. Her mother didn't survive. Instead of letting that grief consume her, Melek channeled it into something that could help others. Working through her school's math club "Matrix" in Izmir, Turkey, she developed an AI system called ONCOMathRIX that uses topological and differential analysis to detect kidney cell carcinoma from pathological images in seconds. It was tested on 537 open-source datasets and achieved a 97% accuracy rate. A professor at Ege University's medical faculty initially saw it as a student hobby project, then realized the system was filling a real gap in the literature. The project has passed the first round of TEKNOFEST, Turkey's largest technology competition, and is currently in the patent process. She is 16 years old.
