Woodruff hadn’t known she was going to be screened for that particular mutation when she first decided to undergo genetic testing. But after several years of investigating it, she’s grateful for the information.

My co-host Ari Shapiro spoke to two experts who think a lot about this – Nita Farahany, professor of law and philosophy at Duke University, where she focuses on the implications of emerging technologies; and Hank Greely, professor of law and biosciences at Stanford University, where he focuses on ethical, legal and social implications of advances in bioscience.
