17-year-old Pennsylvania student Audrey Zheng develops pancreatic cancer test that correctly detects 87% of cases and rules out disease in 87.5% of people

A 17-year-old student from Pennsylvania has developed a promising blood-based method for detecting pancreatic cancer by using magnetic nanospheres to isolate tumor-derived particles from blood samples. Audrey Zheng, a senior at North Allegheny Senior High School, focused on extracellular vesicles that carry molecular information from cells and tested them for cancer-linked KRAS mutations.
