The Mayo Clinic, quote: “There is evidence that consuming large amounts of sugar is associated with an increased risk of certain cancers, including oesophageal cancer. It can also lead to weight gain and increase the risk of obesity and diabetes, which may increase the risk of cancer.”

Nobel laureate in medicine, Otto Warburg, PhD, discovered that cancer cells have a fundamentally different energy metabolism compared to healthy cells. He found that malignant tumours exhibit increased glycolysis (a process whereby glucose is used as a fuel by cancer) as compared with normal cells.  Sugar essentially feeds tumours and encourages cancer growth.  Cancer cells uptake sugar at 10-12 times the rate of healthy cells.

In fact, that is the basis of PET (positron emission tomography) scans, one of the most accurate tools for detecting cancer growth.  PET scans use radioactively labelled glucose to detect sugar-hungry tumour cells.  When patients drink the sugar water, it gets preferentially taken up into the cancer cells and they light up!
