Michael Buble discusses his son’s cancer diagnosis, saying, ‘It transformed what mattered.’

Michael Buble has opened up about how his eldest son’s cancer diagnosis “changed what mattered to me.”

Noah, the “Sway” singer’s three-year-old son, was diagnosed with liver cancer in November 2016.

Noah, now nine, was treated and given the all-clear the following year.

“It, of course, changed me in a big way – it changed what mattered to me, it changed how I saw life,” Buble revealed in a new interview.

“I’d become my alter ego throughout most of my life as an artist, especially on stage.”
