Having just completed months of gruelling treatment for breast cancer, Belle came to me with a question I hear all the time: 'How can I stop the disease from coming back?'

Her sister, who had accompanied her to the appointment, had been scrolling through social media and wanted to know if certain supplements could help. Should Belle cut out sugar completely? Were there foods that could stop cancer returning?

It's an understandable concern. More younger people are being diagnosed with cancer than ever before. And for those who have already faced the disease, the fear that it might come back can be overwhelming.

Unfortunately, social media is awash with advice that ranges from misleading to downright false.

The reality is that there isn't a particular diet, supplement or lifestyle change that can guarantee cancer will never return. But there are steps that can reduce the risk.
