Having experienced her cousin battling breast cancer, Brittany Wenger decided to try and make difference. Brittany started researching about machine learning, and designed a cloud application that detects breast cancer correctly over 99% of the time. Brittany was the Grand Prize winner in the 2012 Google Science Fair for her medical app.

Brittany is just 17 years old, and yet she is already on her way to saving lives. Her project to build an app that tests for breast cancer shows that you are never too young to change the world. If you're 13 to 18 years old and have an interest in science, technology, medicine, or the environment, we encourage you to enter the 2013 Google Science Fair! .
