Argentinian magazine Gente reports that Noah has started chemotherapy, which will go on for four months. Michael Buble's sister-in-law Daniela spoke to the magazine about the state of his condition.
“Cancer is a horrible illness but we have faith in Noah being able to overcome this. We know he will. The time to start a long and very difficult treatment has come but it’s got to be done. They say children are normally strong to put up with chemotherapy and my nephew is a warrior.
"He has the innocence of children and that is good.
"He doesn’t understand too much what is happening. The love people are showing is helping us to see things with optimism and we have a lot of faith.”
The magazine also reported that doctors have said that his chances of beating the cancer are at 90% at the moment.
Michael Buble recently released a statement on Facebook announcing the sad news, and letting people know that he and his wife would be taking time out of work to look after Noah. Michael Buble recently cancelled his BBC Music Awards performance for this reason.
“We have always been very vocal about the importance of family and the love we have for our children," he wrote. "Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well.
“At this difficult time, we ask only for your prayers and respect for our privacy. 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.”
We wish Noah a speedy recovery, and our thoughts are with the family.
