MARLBOROUGH – Christopher Weyant knows the Dana-Farber Institute well. “Cancer has been a central part of our lives dating back to 2003 – when my mom and dad were diagnosed with breast and kidney cancer respectively, six months apart,” said Weyant on his fundraising page for the Jimmy Fund Walk. “Since the age of 9, the Dana-Farber Cancer Institute has provided my family with world-class medical and emotional care.”
