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 some encouraging news.

“I gotta tell you guys just because I’m so stoked, I gotta tell somebody,” Cook said. “I got great news today, my brother’s tumor has stopped growing!” Cook then dedicated the Foo Fighters’ ‘My Hero’ to his brother.
