This food fights cancer

Scientists say the brocol is fighting cancer. They found certain substances in vegetables to block damaged genes that were related to cancer.

Finding can lead to a new strategy for preventing and treating cancer.

Substances called isothiocyanates can be found in brocoli, floret, lettuce, or lescée, and affect the prevention of cancer growth.

But no one knows exactly how these substances work, which is a key to developing an improved strategy in the fight against cancer in humans.
