David Cook: My Brother Adam’s Brain Tumor Has Stopped Growing

David Cook has been quiet about his brother Adam’s struggle with a brain tumor, but during the kick-off to the American Idols Live Tour in Glendale, Arizona on Tuesday night, the ‘Idol’ champ told the cheering crowd, “I gotta tell you guys just because I’m so stoked, I gotta tell somebody. I got great news today, my brother’s tumor has stopped growing!” Cook then dedicated the Foo Fighters’ ‘My Hero’ to his brother. Watch the performance below.
