In February 2009 5 year old Zachary Knighton-Smith was diagnosed with Stage IV Acute Neuroblastoma after doctors discovered a 10 cm tumour in his stomach and smaller growths on his thigh and pelvis. While this would be devastating for most families, this was doubly so for his family because 18 months earlier, his cousin Chelsea Knighton, who was 2 years old at the time, was diagnosed with Stage IV Acute Neuroblastoma after a 12cm tumour was discovered in her stomach. Chelsea had chemotherapy to shrink the tumour and an operation to remove it (which wasn’t 100% successful) followed by further chemotherapy. At the same time, the family switched to an organic, low sugar diet and homeopathetic remedies.
