Celebrity A Year After Brother's Death, David Cook Raises $140K for Cancer Research The Idol alum returns to a charity race for a cause that's close to his heart By Rennie Dyball Published on May 2, 2010 10:00 PM Share Tweet Pin Email Photo: Jeffrey Kolodin One year after losing his brother Adam to a brain tumor, David Cook returned to a place – and a race – close to his heart. In 2009, the American Idol winner served as grand marshal for the Race For Hope, which benefits the National Brain Tumor Society and Accelerate Brain Cancer Cure, despite his brother’s passing just one day before. Returning to the annual 5K in Washington, D.C., on Sunday, Cook tells PEOPLE, “I came back because the cause is important to me and my family, as well as countless others. Brain tumors and brain cancer continues to be one of the most under-funded diseases.” So the singer made sure to do his part, raising $140,000 with his team and fans as part of the $2.3 million the race earned overall.

In addition to running it (“I’m still in the ‘as long as I finish’ mode,” he jokes of his time goal) Cook came in early to play in a charity golf event on Friday and stayed late, taking photos with every survivor at the race. “The last year has been a process,” says the singer of coping with his brother’s death. “It’s all about perspective and remembering what Adam went through so we can work to help avoid anyone else having to do the same.” For more information about the charity, visit curebraintumors.org.
