February 4th is World Cancer Day, and the official Stand Up To Cancer YouTube channel hopes a recent video will receive plenty of shares and up cancer awareness around the globe. The video features 23 renowned celebrities and asks an important question: Who do you stand up for?

The video features the celebs saying the names of friends and family members who have been stricken with cancer. As the disease affects more than one-third of humans around the globe, its reach is impossible to escape, and the video hits home that point through big-name appeal.

The celebs in the video are Tim McGraw, Emma Stone, Konstantin Kryukov, Vanessa Williams, Eric Stonestree, Carson Daly, Ethan Zohn, Brian Williams, Naya Rivera, Jesse McCartney, Bill Hader, Missy Franklin, Seth Rogen, Jon Heder, Marlee Matlin, Dr. Ana Maria Polo, Tom Hanks, Dana Delany, Jordana Brewster, Samuel L. Jackson, Joshua Jackson, Alison Sweeney, and Katie Couric.

The SU2C YouTube channel has gained more than 7.5 million views in almost five years of existence, but it still has under 10,000 subscribers. Awareness is an important step in combating cancer, and keeping tabs on the non-profit’s videos is good way to be aware. It’s a click you won’t regret.
