 Rates of early-onset colorectal cancer have doubled since the mid-1990s, and doctors and researchers are working to figure out why. So today, we're not just going to talk about colorectal cancer, but all forms of cancer, and why, as I said, we are seeing an increase in early-onset cancers. And I'm going to start today with Dr. Kimmy Ng. She's director of the Young-Onset Colorectal Cancer Center at Dana-Farber Cancer Institute in Boston, Massachusetts. Dr. Ng, welcome to On Point. Thank you for having me.
