“Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well,” the singer continued. “At this difficult time, we ask only for your prayers and respect for our privacy. We have a long journey in front of us and hope that with the support of family, friends and fans around the world, we will win this battle, God willing.”

Childhood cancers make up less than 1 percent of all cancers diagnosed each year, according to the American Cancer Society. After accidents, cancer is the second leading cause of death in children aged 1 to 14. But because of major treatment advances in recent decades, more than 80 percent of children with cancer now survive five years or more.
