Magician Criss Angel’s son Johnny Crisstopher’s cancer has returned, the illusionist revealed Tuesday.

In an interview with TMZ, Angel said that Johnny, 5, will be going back to the hospital for treatment following a brief remission. He was first diagnosed with acute lymphoblastic leukemia in 2015.

"Johnny Crisstopher -- he got diagnosed with pediatric cancer before he was 2-years-old -- he’s been in treatment for over three years, he’s been in remission," Angel, 51, told the outlet. "But unfortunately ... he had a relapse and he’s going back into the hospital on Monday."
