Days after Michael Buble's revealed his three-year-old son had been diagnosed with cancer, further details have emerged about the toddler's condition. An Argentine magazine reported on Wednesday (9 November) that Noah has liver cancer.

According to Gente magazine, doctors in Los Angeles diagnosed the singer and wife Luisana Lopilato's eldest child earlier in October following a liver biopsy.

The publication adds that the Noah is believed to have started chemotherapy which is expected to last four months.

Lopilato's – his Argentine wife of five years – elder sister Daniela told the magazine that the early detection was a blessing. "'If God wanted it to be discovered that way, it's because he wants to save Noah. Cancer is a horrible illness but we have faith in Noah being able to overcome this."

She added: "They say children are normally strong to put up with chemotherapy and my nephew is a warrior."

Buble – whose hits include Crazy Love and Just Haven't Meet You Yet – confirmed his son's health status on 4 November, admitting he and his wife had been left "devastated" by the diagnosis.

"We have always been very vocal about the importance of family and the love we have for our children," a statement posted on Buble's Facebook page said. "Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well."

He asked that fans pray for his son's recovery saying: "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."

Buble has pulled out of a number of work commitments including the BBC Music Awards, to focus on supporting his family while Noah receives treatment. Although the 41-year-old crooner is due to host the Brit Awards in London on 22 February, it is uncertain whether he will make the event.
