Daniela Lopilato confirmed that the three-year-old was not suffering from leukaemia, and also revealed the cancer didn't affect his central nervous system.
Luisana's elder sister, a renowned nutritionist who also acts in her spare time, made the revelations as she admitted the entire family was 'broken in half' by the earth-shattering diagnosis.
The Canadian crooner and Argentinian actress Luisana revealed their son's plight in a statement on Friday after speculation he was ill with mumps.

Argentinian journalist Tomas Dente read out a text message from Daniela on a morning TV show which said: 'To tell you the truth I'm devastated. This is very recent.

'The only thing I ask is that you don't speculate because not everyone has children and can understand what this means.

'Michael and my sister will publish more statements and I can't say anymore.

'But it's not leukaemia or the central nervous system as people are saying. It's all I can say.'

The couple did not specify what type of cancer their son is battling but said he is currently receiving treatment in the US.

While they are 'really sad' during this difficult time, they are 'hopeful' and 'staying positive', sources told Us Weekly on Friday.

'They immediately got him very good care and they are hoping and praying for the best. They are getting him the best doctors around,' one source said.
