Maryanne was on a packed train home from work when she got the call.
It was the doctor ringing about her one-year-old daughter, Fiapule.
"We've got results from the tests," the voice said over the phone. "But it's best [to find out] when you're at home, and you're sitting down with your husband."
The mother-of-two had been holding onto hope but "when you hear something like that, I knew it wasn't good news".
She hung up the phone and broke down in tears.
"Straightaway, that's when all the negative thoughts came through.... I just had a quiet cry on the packed train," the 38-year-old told Mamamia.
After calling her husband and asking when he'd be home, all Maryanne could do was wait for the next 30 minutes until her train pulled into the station.
When they finally arrived back at their Sydney home after picking up Fiapule and her other daughter Pua, who was then five, from daycare, the couple gathered around the phone to hear the news.
"All that our ears were listening up for was the word cancer," she recalled.
But the word didn't come out of the doctor's mouth, at first.
"[They said], 'We found a polyp and we tested it and it's come back as neuroblastoma which is a type of tumour'. That's all they had said."
