Chlorophyll can help prevent cancer -- but study raises other questions:

A recent study at Oregon State University found that the chlorophyll in green vegetables offers protection against cancer when tested against the modest carcinogen exposure levels most likely to be found in the environment.

However, chlorophyll actually increases the number of tumors at very high carcinogen exposure levels.

Beyond confirming the value of chlorophyll, the research raises serious questions about whether traditional lab studies done with mice and high levels of toxic exposure are providing accurate answers to what is a real health risk, what isn't, and what dietary or pharmaceutical approaches are useful.
