Lopilato explains that she was filming a movie in Buenos Aires, Argentina, when Noah fell sick. She was told by a local doctor that he had the mumps and swollen glands. But, Noah's pediatrician disagreed with the diagnosis and suggested it might be an infection. After prescribing Noah with antibiotics they decided do a full examination just to be safe.
"They ran lots of tests, blood analysis, everything," Lopitalo emotionally recalled. "When they did an ultrasound, they said they found something in his stomach. [Doctors] told us they weren’t sure what it was, but it was a tumor."
At the time, Bublé was in England in the middle of an important interview, leaving Lopilato to make an emergency decision.
"I couldn’t speak to him by phone. So I got on a flight," she explained, adding that the family has a rule that if anything were to happen to them, they would travel to Los Angeles as a halfway point for both families.
"Without speaking to Mike I took the flight," she continued, revealing that Bublé's close friend is an oncologist in Los Angeles. Fortunately, the singer was able to reunite with his family that same day.
After the diagnosis, Lopiloto and Bublé canceled all scheduled appearances and projects to focus on their family. They remained in Los Angeles for seven months for Noah's treatment.
"There are things that happen in life that make you realize that the most important things that you think are important, really aren't," the actress shared. "The most important thing is to have faith and to be strong. There are nights that I still don't sleep and I pray to God because it's still a long process and the worst is over. Thank God."
Her family, especially her mother, has helped her get through the tough process. "When I was down, my mom told me, 'Be strong, your son will be fine,'" she said.
