She looks at how cancer biologists came to better understand the complex processes, beyond genetics, keeping our bodies in a healthy balance, and leads us through several of the mechanisms our bodies use to keep problem cells in line. She explains how understanding these natural processes could help scientists develop new ways to prevent or stop cancer’s growth. Image: Public domain via Wikimedia Commons
