Kane was a typical active boy who loved to climb, play and "have adventures".
But one day during Easter in 2014, after jumping on the trampoline with his cousins, Kane started to complain of leg pain, began limping and was constantly tired.
"He couldn't tell us where in his leg the pain was," Mrs Ransom said. "When he stopped walking because the pain was too bad we took him to see a doctor.
"We took him to three doctors and a physiotherapist. They all kept saying that he's fine. But he was walking and talking differently. As a parent, I could see that he had changed."
Despite being told by doctors that her little boy was "fine", Mrs Ransom noticed further symptoms developing in Kane indicating that he was ill. He even began turning a slight shade of green.
Following her instincts, Mrs Ransom took Kane, the youngest of her two children, to see the family GP and insisted on a blood test for her son.
"I told him that I wasn't leaving without a blood test, that there was something wrong with my son," she said. "We got a call the next morning and were told that the test picked something up."
Kane was diagnosed with acute lymphoblastic leukaemia. He was rushed to John Hunter Hospital for immediate treatment.
"We were told that if we hadn't taken Kane in when we did, he'd have only had four weeks to live," Mrs Ransom said. "I'd been fighting for five weeks to find out what was wrong with him. That was gut wrenching."
Following two years of treatment, of being in and out of hospital, Kane was given the all clear.
However, the joy of remission was short-lived when his cancer returned 18 months later in November 2017, this time more aggressive than before.
Now five years after that initial diagnosis, Kane, aged 8, is still going through intensive treatment. He is due to finish his next round of treatment in May 2020.
Mrs Ransom said Kane's treatment is going well, and that her son remains positive and adventurous as ever.
Kane is now an ambassador for the Children's Cancer Institute's unique fundraising initiative called CEO Dare to Cure.
More than 90 CEOs and business leaders will step out of their comfort zone in Sydney on September 6 and challenge themselves to undertake thrilling dares, all in the name of cancer research.
Some of the dares, which will be undertaken in Sydney's Botanical Garden, include jumping in an ice bath, walking across hot coals or glass, receiving a public tattoo, flying trapeze and letting snakes slither across them.
All funds raised by the CEO Dare to Cure challenge will support research by the Children's Cancer Institute.
However, it is not just business leaders who undertake challenges. Ambassadors such as Kane and their families will, too.
Kane has signed his mum, dad Brendan and big sister, Naveen, 10, up for some of the dares.
"Kane wants to hop in the snake bath and shave his head," Mrs Ransom said. "He said he wants to give back and raise awareness about children's cancer. It brings him joy. He really loves being an ambassador."
Mrs Ransom said Kane's other motive in being an ambassador was to help him achieve his ultimate goal - land a role in the Star Wars film franchise.
By sharing Kane's story, the Ransoms hope to raise further awareness about children's cancer and the groups such as the Children's Cancer Institute, Red Kite and Camp Quality that help families deal with a diagnosis.
Since Kane had been diagnosed, Red Kite has provided assistance with fuel vouchers for the family who have to make regular trips to hospital and the Ronald McDonald education program had provided Kane, in year 2, with a tutor.
Both Kane and sister Naveen have been to Camp Quality, which Mrs Ransom was a great help for her children.
She also praised the team at John Hunter Hospital's oncology and haematology department for its support.
"The team there is absolutely brilliant," Mrs Ransom said. "The do such a wonderful job and are always so supportive."
