Fucose And Cancer

I found this information about fucose and cancer, from:

Fucose appears to inhibit cancer growth and metastasis. For example, fucose inhibited rat mammary tumor cell growth in vitro. Different concentrations of fucose uniformly produced a suppression in the growth rate and a change in the morphology of cells grown in tissue culture.33 Fucose also inhibited mouse tumor cell-induced platelet aggregation, a process important in cancer cell metastasis.34 A natural product derivative of fucose (2-deoxy-L-fucose) inhibited leukemia and mammary tumor cell growth in cell culture systems in vitro.35 Injection of 600 mg fucose in rats with a chemically-induced mammary tumor resulted in suppressed tumor growth, and serum and tumor levels of fucose were increased in the treated animals.36 This result was repeated when fucose was infused intravenously in this same rat cancer model.37 38 After 23 days of continuous intravenous infusion of fucose in rats, bone marrow, liver, kidney, and spleen were normal microscopically.38
