D. Another Reason To Like Broccoli ...

Narrator: This is Science Today. Researchers at the University of California, Berkeley have found a possible cancer therapy on our dinner plate. Gary Firestone, a professor of molecular and cell biology, says there's a chemical called indole-3-carbinol in broccoli and similar vegetables, which stopped tumor growth in studies on breast cancer.

Firestone: So, we think the value of this compound won't be in having one eat it, but maybe more as, for example, in injections at tumor sites and more in the area of once you have a tumor - and this is all theoretical - might be potentially used to combat the growth once it's already formed.

Narrator: Firestone says since the compound is derived from a common plant like broccoli, it would be cheaper than various drugs on the market which are extracted from plants in the rainforest.

Firestone: It may be therefore, more accessible to most people because of the economics and buying a lot of broccoli for extracting this material is fairly cheap and I think that that's actually very important, also. If it does work, your vegetable garden might be your source of this material.
