Today is World Cancer Day, which was created by the World Health Organization to raise awareness about one of the world's leading causes of death. And in an effort to raise awareness of not only cancer, but all major health issues, we're kicking off a health-specific round of Video Volunteers.

You know the drill: just pick a health organization that you care about (or find one on the Video Volunteers channel), make an under-three-minute video promoting their work, and the top three will be featured on the YouTube homepage at the end of the month. Our guest curator this month is musician Jesse McCartney, who took the time to talk about his favorite health org, Stand Up 2 Cancer, and why you should make a video for your health nonprofit of choice:



If you're passionate about raising money to buy malaria nets, want to increase awareness about AIDS/HIV or can help an organization by vlogging about life as a diabetic, we want to see your videos. Submit them at www.youtube.com/videovolunteers by February 23.
