The Pan-Mass Challenge's (PMC) annual bike ride fundraiser broke records with this year's $63 million gift to the Dana-Farber Cancer Institute. The PMC, led by Billy and Meredith Starr, has exclusively raised $717 million for Dana-Farber over its 40-year history. Dana-Farber president and chief executive Dr. Laurie Glimcher explains how the funds impact patient care and research. Over 150 Dana-Farber employees participated in the last ride, including Dr. Katherine Janeway, who was a cancer patient herself.
