Michael Bublé has revealed he almost quit music after his son Noah was diagnosed with cancer.

The 42-year-old singer told the Herald Sun he never thought he'd come back to the industry.

"I've been to hell ...Family is what matters. The health of my children is number one."

Bublé and his model wife Luisana Lopilato announced in November 2016 that their eldest son who was 3 at the time, was battling cancer.

Bublé released a statement saying the family had along road ahead and asked for privacy while dealing with the diagnosis.

"Luisana and I will devote all our time and attention to help Noah to get better, for now suspending our professional activities."

Noah has fortunately recovered and Bublé has returned to work.

The couple are now expecting a new sibling for Noah and his brother Elias who was born in January 2016.

In March Bublé told Entertainment Tonight Noah's battle with stomach cancer had been an emotional roller coaster.

"I think life sort of teaches you these hard lessons sometimes.

"Part of that lesson is that it allowed me to really have perspective, and to really enjoy more than I ever have in my life."
