Reuters - Cancer cells slurp up fructose, US study finds
Reuters reports: "Heaney said his team [...] grew pancreatic cancer cells in lab dishes and fed them both glucose and fructose. Tumor cells thrive on sugar but they used the fructose to proliferate. 'Importantly, fructose and glucose metabolism are quite different,' Heaney's team wrote. [...] U.S. consumption of high fructose corn syrup went up 1,000 percent between 1970 and 1990, researchers reported in 2004 in the American Journal of Clinical Nutrition."

Comment: I long ago limited my intake of natural sugar but I know my diet is rich in high fructose corn syrup, best start limiting that as well.
