Anti-cancer compound in vegetables found to block late-stage breast-cancer cell growth
...-known anti-cancer agent in certain vegetables has just had its reputation enhanced. The compound, in broccoli and other cruciferous vegetables, has been found to be effective in disrupting late stages of cell growth in breast cancer.

... people can chew the gum for preventive health, or just to enjoy a piece of gum, Dr. Hsu said, noting that the cost is comparable to that of regular gum. He suggests chewing a piece at least 15 minutes for optimal health benefits.
