Small errors can quickly escalate to have large repercussions. When it comes to cancer, molecular changes to DNA can trigger chain reactions that cause cells to go awry and spread uncontrollably. Dr. Louis Staudt works to identify such changes, known as genetic mutations, and find ways to stop them from snowballing into a deadly disease. In this episode, Dr. Staudt recounts the story of how he differentiated subtypes of lymphomas to develop a treatment for patients as an early success of precision medicine.

Dr. Staudt is a principle investigator and the director of the Center for Cancer Genomics at the National Cancer Institute. He was recently elected into the National Academy of Medicine. Learn more about his research at https://irp.nih.gov/pi/louis-staudt.
