No one is ever fully prepared to deal with the overwhelming and complex journey that comes with a cancer diagnosis,” said Cooper, who lost his father, Charles Cooper, to lung cancer in 2011. “Stand Up To Cancer works tirelessly to support those at the forefront of the fight against cancer. SU2C’s mission, to ensure that all cancer patients become cancer survivors, is one that is very close to my heart. I am proud to join forces to make this vision a reality and to be part of this movement that is dedicated to getting lifesaving treatments to cancer patients faster.”
