The Argentinian publication claimed that the Canadian crooner's eldest was diagnosed on November 1, after Noah underwent a liver biopsy, following an examination at a clinic in Buenos Aires.
It's believed that he will undergo chemotherapy for four months. Thankfully the reports claims he has a 90 per cent chance of recovery.
Speaking to the magazine, the singer's sister-in-law Daniela Lopilato confirmed the little boy has already begun chemotherapy.
"If God wanted it to be discovered that way, it's because he wants to save Noah," Daniela said.
"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 that children are often strong enough to withstand chemotherapy… and my nephew is a warrior."
On Friday, November 4th, Noah's parents revealed their son's health battle in a statement.
"We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US," Michael, 41, announced on his Facebook page.
"We have always been very vocal about the importance of family and the love we have for our children. Luisana and I have put our careers 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 is and hope that with the support of family, friends and fans around the world, we will win this battle, God willing," his joint statement with his 29-year-old wife read.
In light of his family situation, Michael has pulled out of all work commitments, including his upcoming performance at next month’s BBC Music Awards.
"We send Michael and his family our very best wishes," BBC Music director Bob Shennan said in a statement.
The jazz singer is yet to confirm whether he will still host the 2017 Brit Awards next February and Canada's Juno Awards in April.
