Michael Buble's wife Luisana Lopilato has broken her silence on their son's cancer battle to reveal that the four-year-old Noah "is well".

In November 2016, the toddler was diagnosed with liver cancer following a biopsy at a clinic in Buenos Aires in November and immediately started a four-month course of chemotherapy.

Speaking at a press conference for her new film, Those Who Love, actress and mother-of-two Lopilato said she was overwhelmed by the amount of support her family had received after her husband released a statement saying he and his wife had been left "devastated" by the diagnosis.

"Thank God, my son is well. When things like those that happened to us occur, your take on life changes," Lopilato said.

She went on to add that her son's health status had put things into perspective. "It happened to us. Now I value life much more, the now and the today," she said. "I would like to thank people for their support, for the prayers they said, for their love. And I want them to know that they reached us and that it helped us a lot to come through this."

The 29-year-old, who tied the knot with the Crazy Love crooner in 2011, also thanked producers of her new movie for halted filming so she could concentrate on her son as he fought the disease."It's difficult for me to speak about this, it's very recent and I'm still a bit sensitive about the subject."

Although she was elated that her son was on the road to recovery, she admitted they had a long journey ahead which involved regular check-ups."But we are very happy. We are looking forward to thinking about the future, to seeing our children grow. Seeing Noah grow and being happy gave me the strength to return and finish this film.

"My faith in the fact God had a miracle helped me. I became strong so my son would get better. I transmitted that to all my friends and family."

Up until now, the couple had only used Facebook to update fans. After their initial announcement, they were prompted to issue another statement on 3 January after an Argentinian journalist reported that Noah's aunt, Daniela Lopilato, had told him: "The cancer has gone."

"We are so grateful to report that our son Noah has been progressing well during his treatment and the doctors are very optimistic about the future for our little boy," they said said at the time."He has been brave throughout and we continue to be inspired by his courage. We thank God for the strength he has given all of us. Our gratitude to his doctors and caretakers cannot be put into words."
