Cruciferous vegetables and cancer

Nutrients In Certain Vegetables May Provide Cancer-fighting Benefit ScienceDaily 3/17/07 "Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to not only stop human prostate cancer cells from growing in mice but also may cut off the formation of blood vessels that "feed" tumors, says a University of Pittsburgh Cancer Institute study...Dr. Singh's study is based on phytochemicals, called isothiocyanates (ITCs), found in several cruciferous vegetables and generated when vegetables are either cut or chewed. His laboratory has found that phenethyl-ITC, or PEITC, is highly effective in suppressing the growth of human prostate cancer cells at concentrations achievable through dietary intake..."Angiogenesis is a major issue in cancer metastases," said Dr. Singh. "Our results provide promising preliminary evidence that constituents of many edible cruciferous vegetables may slow down, or even halt, this process.""

Quite amazing that at dietary levels these vegetables can have a strong antiangiogenesis effect.
