Thursday Feb 4, 2016 (foodconsumer.org) -- Eating sugar increases risk of breast cancer and its lung metastasis,  according to a new report in Cancer Research.The study finds that sucrose or sugar increases risk of breast cancer by increasing the production of 12-lipoxygenase, which catalyzes oxidation of arachidonic acid into 12-hydroxy-5Z,8Z,10E,14Z-eicosatetraenoic acid (12-HETE), a metabolite found high in breast cancer mass.   Specifically, fructose which accounts for 50% of sucrose (the remaining 40% is glucose) was found to be responsible for lung metastasis and 12-HETE production.  The study seems to suggest that breast cancer patients should avoid eating sucrose or sugar.
