After his brother Doc's death in 2017 from colorectal cancer, Joe Mahaffey has assumed the role of passionate advocate. 

In March of 2018 Joe traveled to Washington, D.C., along with close to 200 fellow patients, survivors and caregivers, for Fight CRC's annual Call-On Congress. Back home in North Carolina Joe has been working to fulfill one of his brother's dreams; to have a colorectal cancer license plate available for North Carolina residents. The Blue Ribbon Warrior license plate is one of the focuses of the non-profit the Mahaffey brothers created, the Blue Ribbon Warrior Foundation. 

Lee also interviewed Dr. Prasanth Reddy, MD. Dr. Reddy is the VP of Medical Affairs for Foundation Medicine. Foundation Medicine  is the company behind FoundationOne CDx; the first FDA-approved broad companion diagnostic (CDx) that is clinically and analytically validated for solid tumors.
