More than 50 media platforms will air the special, including four major broadcast networks; it will also be available on demand and streaming.

In the announcement, SU2C cofounder Katie Couric noted, “We started this movement in 2008 to save lives and it is remarkable to see that in 15 years our scientists have accomplished this goal through breakthrough research that intercepts and treats cancer in ways we never thought possible.”

Couric, who will also appear in the special added, “There is more work to do to cure cancer and every dollar counts; we will not stop until we make every cancer patient a long-term survivor.”
