Gideon Purchase was only six months old when he was diagnosed with stage 4 high-risk neuroblastoma.
He had tumours in 84 per cent of his bone marrow and was given a 50 per cent five-year survival rate. The little boy faced the fight of his life.
Two years on and he is cancer free, thanks to a pioneering clinical trial.
His family documented his journey on their Facebook page and recently announced his latest scans were clear of cancer.
It all began when his parents Katie and Gary first noticed their little boy had lost his appetite, wasn't sleeping and was distressed. And then they found large yellow bruises on his body and a bump on his head.
When they took him to St Jude Children's Research Hospital in Memphis they were informed he was very unwell.
"It's literally as bad as it gets," Mrs Purchase told TODAY.
According to his doctor his tiny body was riddled with cancer.
"His entire face and skull was full of cancer, and all of his bones were full of cancer," his doctor Sara Federico said.
"He had a large tumour that was present in the middle of his body."
With the advice of the medical team, the family decided to enter a clinical trail to give him the best shot of surviving the insidious disease. The treatment meant he was given chemotherapy along with an antibody – and almost immediately he showed marked improvements.
Tumours from his face, arms and legs disappeared in the first six weeks. A bone marrow transplant and radiation was then used to kill off the remaining cancer cells.
His dad wrote on the family's GoFundMe page that his son was also given a drug commonly used for acne – Accutane – which helped suppress the growth of aggressive cancer cells.
He now has no tumours in his bone marrow and now the little boy, who has spent much of life in hospital, can finally go home to live with his family.
"You yearn for the day when you're not toting around an entire IV tree behind your kid," Mr Purchase said.
"And then it happens, and you just kind of sit there like, 'Wow. We made it'."
He still has a few challenges ahead of him, but after what he's faced the family know he has the strength to overcome them. In fact, the experience has made them all stronger.
"It makes you appreciate the little things," he said.
"Suddenly life's problems just don't seem like a big deal anymore."
