Aubrey Peeples raising awareness about pediatric cancer

Singer and actress Aubrey Peeples has a new mission in life: to raise money and awareness about pediatric cancer. Peeples, who is best known for her role in the TV show "Nashville," is this year's ambassador for Hyundai's Hope on Wheels fundraiser.

She performed for some patients at the Pediatric Cancer Center at New York-Presbyterian Columbia University Medical Center.

12-year-old Hannah Adams from Florida and Ryan Darby of Maryland were diagnosed with cancer when they were 5 and 6 years old. Their cancer is in remission. Now they are sharing their struggles and hope with other children stricken with cancer. They are the national youth ambassadors for Hope on Wheels.

Pediatric cancer patients rely heavily on fundraising dollars.
